Kang was born Kim Ha-neul in Busan, South Korea, the eldest of two brothers. His parents were both former theater actors; his father graduated from the Seoul Institute of the Arts, and his mother graduated from the Department of Theater and Film at Kyungsung University. His mother also previously worked as a fashion model. Kang developed an interest in the performing arts during middle school. Although theater was a familial presence from a young age, his direct involvement began during his second year of middle school when he participated in a church theater production of A Bowl of Udon as a prop team member. He later recounted a strong emotional response, including crying, during the curtain call. Kang's initial exposure to television entertainment occurred in 2005 when he and his father were featured on the KBS1 Morning Garden, where they achieved three consecutive wins in the family singing contest. The program's host, announcer Lee Geum-hee, later remarked that their performance was particularly memorable. Kang initially attended a regular high school, where he joined the acting club. Upon expressing his intent to pursue acting professionally, he received full support from his parents. To focus on his artistic development, he subsequently transferred to the National Traditional Arts High School, where he majored in music and theater. Kang was independent from a young age, having worked part-time consistently since middle school. His need to earn his own tuition following his move from Busan made him continue as a part-timer. This experience is cited as contributing to the development of his perceptiveness.

Kang began his acting career in musical theatre using his birth name, Kim Ha-neul. His stage debut occurred in 2006 at the age of sixteen with the musical The Celestial Watch, during his first year of high school. Securing a lead role in his first musical reportedly led to the development of stage fright. A teacher advised him regarding the constraints of the stage, stating: "There is no place to hide on the stage. You either win and take control, or you lose and give up." This advice prompted Kang to relearn basic skills in acting, like walking, hand movement, and speaking to overcome his anxieties. In 2007, at the age of seventeen, Kang secured a main lead role in the KBS Sunday drama My Mom! Super Mom!. For his first scene, which involved playing baseball—a sport he was unfamiliar with—he dedicated a week to practicing at a batting cage. His preparation resulted in a performance that garnered praise from the director. He was cast as Choi Hoon, a popular high school student noted for his academic achievement and appearance, a role for which he was selected from approximately 800 candidates. "It was a transitional period for me. I didn't feel ready for the acting, and I didn't like being thrust into the public eye through the drama. I really wanted to learn more by doing theater. So even as I was auditioning for My Mom! Super Mom!, I kept wanting to do theater. In the end, after the audition, I called the director and politely asked them if they could let me drop out, as I didn't want to do it." Despite this unusual refusal from a novice actor, the director persuaded Kang to accept the role. Kang ultimately concluded that his hesitation stemmed from personal insecurity rather than dissatisfaction with the genre. Driven by a sense of responsibility to his supporters, he committed to the project with the determination to exceed his limitations and enhance his skills. Following the completion of the drama, however, he returned to the stage. He successfully auditioned for and was cast as Lee Il in the musical Carpe Diem. In 2007, Kang made a comeback to television by joining the cast of the KBS daily rural drama Hometown Over the Hill, portraying Kang Jong-hee, the head family's youngest son. Having already begun his professional career before pursuing higher education, he enrolled at Chung-Ang University as a theatre and film major in 2008. He subsequently took an extended leave of absence from his studies to focus on his acting commitments. In 2009, Kang was cast as an understudy for the musical Thrill Me, performing the role of Richard on April 10 and 17. That same year, he successfully auditioned for the rock musical Spring Awakening. From June 30, 2009, to January 10, 2010, Kang played the role of Ernst in Spring Awakening, appearing in a cast that included Jo Jung-suk and Kang Mu-yeol (double cast as Moritz), as well as Joo Won (as Melchior). Despite cast changes and absences among his colleagues, Kang performed in every show, totaling 266 performances, a challenging yet fulfilling experience for him. Actor Hwang Jung-min who had observed Kang's performance in Thrill Me, recruited him for Sam Company immediately following the conclusion of Spring Awakening. Founded by Hwang and his wife in 2010, Kang became the agency's second signed actor after Hwang. That same year, Kang was admitted to the 50th Batch of the Theater Department at Chung-Ang University. Consequently, his character in Hometown Over the Hill was written out of the drama's storyline, departing to pursue further studies in Seoul. Kang returned to the musical Thrill Me, this time taking on the role of Nathan, having previously played Richard in 2009. His performance as Nathan was critically assessed as dominating the stage due to his stable emotional portrayal, breath control, and vocalization. Also in 2010, Kang successfully auditioned for Lee Joon-ik's film Battlefield Heroes. The film is a sequel to Lee's earlier work, Once Upon a Time in a Battlefield, and focuses on the Silla–Tang Allied Forces' campaign to attack Goguryeo's Pyongyang fortress. Kang was cast as Namsan, the youngest son of Yeon Gaesomun of Goguryeo, who is depicted as conflicted between his two older brothers' opposing stances on negotiation versus warfare. "I'm still grateful to director Lee Joon-ik for making my first set so beautiful. One day after filming, we were drinking together when he suddenly asked me and [Lee] Kwang-soo to be friends. I said, "Director, how dare we be friends with you?" He replied, "Why? Foreigners are friends with everyone, even their grandparents and children, so why can't we be friends?" Because of that connection, even after Battlefield Heroes was finished, I would go to the director's office to hang out and drink with him. It was so nice." Kang also secured a supporting role through audition in the film You're My Pet (2011), which starred actress Kim Ha-neul. He was cast as Yang Young-soo, a musical actor and a friend of the male lead, In-ho (played by Jang Keun-suk), who is responsible for guiding In-ho in matters of love. In November 2010, he formally adopted the stage name Kang Ha-neul, replacing his birth name, Kim Ha-neul, to prevent confusion with the actress Kim Ha-neul.

In 2019, Kang made a comeback to television with the KBS2 TV series When the Camellia Blooms alongside Gong Hyo-jin. He portrayed Hwang Yong-sik, a police officer with a strong instinct for finding and beating up criminals. He moves back to his hometown Ongsan after being demoted. The drama achieved the highest ratings for a miniseries that year, garnering critical acclaim and numerous accolades, including the Baeksang Arts Award for Best Actor – Television for Kang. He also won several other best actor awards and was ranked second (behind his co-star Gong Hyo-jin) in the Gallup Korea's Actor of the Year survey. In November 2019, Kang's contract with SEM Company, his agency since 2010, expired. He subsequently joined TH Company, a newly established agency founded by his former manager. Kang then joined the second season of the travel documentary Traveler with Ahn Jae-hong and Ong Seong-wu. From November 30 to December 12, 2019, the trio filmed a two-week journey in Argentina, visiting locations such as Iguazu Falls, Perito Moreno Glacier, and Patagonia. In January 2020, he returned to the theater in Kang Dong-yeon's Fantasy Fairy Tale, a work that combines play-within-a-play material, dance, mime, music, and acting. Kang acted as the love clown, a character with a pure and emotional personality. The play ran from December 21, 2019, to March 1, 2020, at Dongduk Women's University Performance Arts Center Cotton Hall. This marking his first stage performance since Harold and Maude in 2015. • Illustration — Kang in 2021 In 2021, Kang returned to the silver screen with Waiting for Rain, playing Young-ho, a man who lives aimlessly while corresponding with a lover via letters.

Kang's transition to television led to his initial opportunities as an advertising model. In 2012, his role in the drama To the Beautiful You secured him commercials for Mercilon with Han Ga-young in September and Amos Professional with Cha Soo-yeon in October. The subsequent success of the drama Monstar brought further endorsement offers, including a "Love Taste" commercial for Danish Drinking Yogurt with Ha Yeon-soo.

The year 2011 marked his new beginning as an actor under the stage name Kang Ha-neul. He was credited with this new stage name for his debut film, Battlefield Heroes, which was released in January of that year. In September 2011, Kang appeared as Eunuch Gu-dong in the musical Prince Puzzle. The production, written by Han A-reum and directed by Seo Jae-hyeong of Jukdorok Dalinda, was notable for being staged within the Sungjeongjeon hall of Gyeonghuigung rather than a conventional theatre. Kang noted, "I chose this work because I wanted to work hard until I die." Kang initially believed he was being offered the role of the Crown Prince in Prince Puzzle; Kang described his role as physically demanding. Noticing his exhaustion, the stage manager advised him to read audience reviews for motivation, implying the production's critical success. Director Lee Joon-ik attended a performance and praised Kang's acting, stating, "You're really good, as expected." In 2012, Kang was cast in the original musical Black Mary Poppins, produced by Kim Soo-ro. Written, directed, and composed by Seo Youn-mi, a rising dramatist in Daehangno, the thriller was inspired by the Mary Poppins series by P. L. Travers.

In November 2012, Kang participated in the third Korean production of Stephen Sondheim's Assassins, performing alongside Hwang Jung-min. For Kang, participation in a Sondheim work fulfilled a long-held dream, despite the challenging nature of the complex melodies and unusual time signatures. He played the dual roles of the Balladeer and Lee Harvey Oswald. The production ran at the Yonkang Hall of Doosan Art Center until February 3, 2013. That same year, Kang also returned to the small screen, starring in the television dramas To the Beautiful You (2012) as Min Hyeon-jae, a high jumper who develops a rivalry with the male lead. In 2013, he was cast as the lead character Jeong Seon-woo in the Mnet's music drama Monstar, directed by Kim Won-seok. The role required him to learn to play the cello, bass guitar, and contrabass. He dedicated himself to practicing these instruments, sacrificing rest by only sleeping for an hour or 30 minutes. Despite the challenges, he was grateful for the director's faith in him and the praise for his efforts. Following the conclusion of Monstar, Kang made a special appearance in the MBC drama Two Weeks as Kang Seong-jun, the autistic son of Jo Seo-hee (played by Kang Hye-ok). He then took on the role of Lee Jun-kyung, an illegitimate son of low yangban status, in the MBC Drama Festival one-act drama Unrest, which aired on October 3. His character pursued the truth behind an unjust death, allowing Kang to portray the anguish caused by the Joseon Dynasty's caste system. Kang's portrayal was praised for showcasing his talent through nuanced facial expressions and emotional depth, effectively conveying the character's inner conflict and grief. In July 2013, Kang secured a supporting role in writer Kim Eun-sook's drama The Heirs (2013), playing Lee Hyo-sin, the charismatic tsundere son of the Prosecutor General and the student council president of Imperial High School. He starred alongside Lee Min-ho, Park Shin-hye, Krystal, Kim Woo-bin, Kim Ji-won, and Park Hyung-sik. Kang had his first onscreen kiss scene in the drama. The Heirs achieved significant success, with domestic ratings peaking at 28.6% and accumulating over one billion views on the Chinese streaming platform IQIYI, leading to widespread recognition for Kang. In 2014, Kang was cast in the series Angel Eyes, where he portrayed the younger version of the protagonist, Park Dong-joo, with Lee Sang-yoon portraying the adult version. The drama aired on SBS from April 5 to June 15, 2014, on Saturday and Sunday. For this role, Kang received the New Star Award at the 2014 SBS Drama Awards. His first lead role in a feature film followed with the release of Oh In-chun's film Mourning Grave which was released in theaters on July 3, 2014. The film combined elements of horror, romance, drama, and comedy, set in a rural school. Kang starred as In-soo, a reclusive student with the ability to perceive ghosts, a college friend Kim So-eun's character. He collaborated again with director Kang Won-seok in his series Misaeng: Incomplete Life, portraying Jang Baek-gi, a permanent employee on the Steel Team at One International. The drama's success led to a surge in Kang's recognition, culminating in him winning the Popularity Award at the 2015 Cable TV Broadcasting Awards.

In 2015, Kang made his debut in a two-hander play, Harold and Maude, alongside veteran actress Park Jeong-ja. Adapted from Colin Higgins' novel, the production explores the intergenerational friendship and affection between Harold, a suicidal 19-year-old, and Maude, an 80-year-old embracing death. It had been previously performed in Korea under the title 19 and 80 starting in 2003. Over the years, Park Jeong-ja has consistently portrayed the role of Maude, while the role of Harold has been played by different actors in each production. The 6th Korean production ran from January 9 to February 28 at the Deloreum Theater of the National Theater of Korea. Kang, playing Harold, commented, "I may be disposable, but I will strive to be an unforgettable disposable Harold. I came across this work and Teacher Park Jeong-ja when I needed to study more and wanted to fill the feeling that something was empty. When I heard that Teacher Park Jeong-ja would be appearing, I naturally decided to appear as well. When we read the script together, the really good lines felt like they were being spoken to me by Teacher Park Jeong-ja, so I felt really comfortable when acting." • Illustration — Kang in 2015 That same year, three of Kang's films were released sequentially. His first biopic, musical film C'est si bon premiered on February 5. The film chronicles the folk music movement centered at the C'est Si Bon music center, which introduced renowned folk music artists such as Cho Young-nam, Yoon Hyeong-ju, Song Chang-sik, and Lee Jang-hee. Kang portrayed Yoon Hyeong-ju, a member of the Twinfolio band. Having been exposed to Yoon Hyeong-ju's music through his father, Kang's vocal talent was highlighted as he successfully replicated Yoon's clear, melodious voice and precise enunciation. On March 5, 2015, Ahn Sang-hoon's period film Empire of Lust was released. Kang played Jin, the King's son-in-law, a character barred from politics and engaged in hedonistic pursuits. It was his first time filming an intense and violent bed scene, which was a challenging experience. Despite the actress reassuring him that it was just acting, he felt guilty and remorseful afterwards. Shortly thereafter, the coming-of-age film Twenty, directed by Lee Byeong-heon, was released on March 25. Kang starred as Kyung-jae, a studious university student aspiring to a corporate career. For his performance in Twenty, Kang received nominations for Best New Actor at the Baeksang Arts Awards, Blue Dragon Film Awards, and Grand Bell Awards. He subsequently won Best New Actor at the 2015 Golden Cinematography Awards, the Korean Film Actors' Guild Awards, the Korea World Youth Film Festival, and the 2016 Chunsa Film Art Award. Due to his commitment to appear at the Blue Dragon Film Awards, Kang initially thought he couldn't join the Youth Over Flowers trip. However, he was surprised by the team and taken right after the award show to join the other actors on November 26, 2015. Youth Over Flowers Iceland was initially announced with three cast members: Jung Sang-hoon, Jung Woo, and Jo Jung-suk.
