He debuted as the leader of the boy band Super Junior in November 2005 and since then has participated in its subgroups Super Junior-T, Super Junior-Happy, Super Junior-L.S.S., and Super Junior-83z. He began his career as a television presenter on the music show M! Countdown. He is best known for his role in presenting Strong Heart, Star King, The Best Cooking Secrets, I Can See Your Voice, and Idol Star Athletics Championships. He is also a regular figure in the South Korean year-end awards; he has presented Golden Disc Awards three times, Gaon Chart Music Awards six times, and Asia Artist Awards six times. He regularly hosts the Dream Concert and the Asia Song Festival annual concerts.

Leeteuk was born on July 1, 1983, as the second child of Park Yong-in and Yoo Suk-yeong. His elder sister, Park In-young, is a singer and an actress. His parents divorced in 1998. He has spoken about his parents' relationship publicly on several television shows. He attended Chungwoon University and graduated with a bachelor's degree. He is also an alumnus of Gachon University.

When Leeteuk traveled to Apgujeong-dong to sightsee in early 2000, a talent scout approached him and recommended he audition for SM Entertainment's Starlight Casting System. After several test recordings and performances, he signed with SM Entertainment and became a trainee. In the same year, he appeared as an extra in the drama All About Eve which aired on MBC TV, and briefly modelled for Pepsi in 2002. In 2003, he was put into the five-member boyband Smile with future bandmate Donghae, which aimed to rival the group TVXQ. The project was dropped, and they were put into the rotational group Super Junior along with ten other boys. Being older than the other trainees, Leeteuk became the group's leader. Leeteuk has explained that he uses a stage name because of his desire to have a name with the same effects as Kangta, and to prevent confusion between veteran actress Park Jung-soo and himself. His stage name Leeteuk, means "special". He previously rejected two of the stage names designated for him by his agency. The agency's then-chairman, Lee Soo-man, called him "a special child" and said the name Leeteuk suited him better.

• Illustration — Leeteuk (second from right) performing on stage with Super Junior in 2011 Leeteuk officially debuted as part of the 12-member project group, Super Junior 05 on November 6, 2005, on Seoul Broadcasting System's (SBS) music program Popular Songs, performing their first single, "Twins (Knock Out)". Their debut album SuperJunior05 (Twins) was released a month later on December 5, 2005, and debuted at number three on the monthly MIAK K-pop album charts. Originally, the band was meant to have rotational line-ups, much like the Japanese girl group Morning Musume, but the idea to form new generations of Super Junior was dropped after fans objected. Following the addition of a thirteenth member, Kyuhyun, the group dropped the suffix "05" and officially became Super Junior. The re-polished group's first CD single "U" was released on June 7, 2006, which was their most successful single until the release of "Sorry, Sorry" in March 2009. In February 2007, Leeteuk was placed in the trot-singing subunit, Super Junior-T. The subunit debuted with the single "Rokkugo", which quickly reached number one on the weekly music chart and held the spot for two consecutive weeks. A year later, Leeteuk became a member of Super Junior-H, a subunit focusing on bright and cheerful music, in contrast to the genre of the songs released by the core group. Besides music, he also participated in Super Junior-centric television shows like Mystery 6 and Full House. He made his first film appearance with Super Junior members in Attack on the Pin-Up Boys in 2007, playing the role of the school's panda mascot. Apart from Super Junior activities, he has hosted several television shows. In 2005, he became the host of a weekly music show, M! Countdown, his first gig as a host, with bandmates Shindong and Kangin. This eventually landed him his first solo hosting act on the reality show Leeteuk's Love Fighter, which aired on the cable television channel Mnet in 2008. He received praise for his work as a newcomer and received a plaque of appreciation from the show's crew members on his last appearance on the show. • Illustration — Leeteuk during Kiss the Radio public broadcast in 2009 Leeteuk became a radio DJ for KBS Super Junior's Kiss The Radio (Sukira) with Eunhyuk in August 2006.

Between 2008 and 2009, he hosted several television programs including three variety shows which aired on KBS2; Road Show Quiz Expedition, Challenge! Good Song, and Challenge! Golden Ladder —co-hosting with several senior television presenters such as Jee Seok-jin, Lee Hyuk-jae, Boom, and Kim Shin-young. From 2009 onwards, Leeteuk, Eunhyuk, and Shindong were regular guests on SBS's Strong Heart, where they hosted a special segment, Boom Academy, headed by Boom. In October 2009, when Boom enlisted for mandatory military service, Leeteuk took over his role and the segment's name was changed temporarily to Teukigayo, or Teuk's Academy. As of the April 10, 2012, broadcast, following the change in MCs and the departure of Shindong from Strong Heart, the show was re-vamped with Leeteuk and Eunhyuk billed as two of the 'six-fixed guests'. In 2010, he appeared as one of many hosts of Waving the Taegukgi, a special program to support the South Korea national football team at the 2010 FIFA World Cup.

He released the single "Grumbling", a duet with f(x)'s Krystal, through the show. Leeteuk was also the MC for MBC's Love Chaser and SBS's Oh! Brothers, further cementing his position as an emerging host for the country's terrestrial television channels. Since 2009, he has been a frequent guest on Star King, with other Super Junior members. In 2011, following Kang Ho-dong's retirement from the entertainment industry, Leeteuk and Boom took over as co-hosts of Star King. From September to November, Leeteuk played the role of a father in Hello Baby season 4, a reality-variety show where the cast had to take care of a baby, with girl group Sistar becoming the baby's mothers.

He received praise for his witty remarks during the ceremonies. He was subsequently selected to host the 30th Golden Disc Awards with Jun Hyun-moo and Krystal Jung, and several more editions of the Gaon Chart Music Awards—the 5th edition with Yura, the 6th with Solar, the 7th with Dahyun, the 9th with Itzy's Lia, and the 10th edition, also with Lia.

He was a field reporter in the 2012 Swimming Championships. Since hosting the two editions in 2015, Leeteuk had become a fixture in the series along with senior presenter Jun Hyun-moo as he had hosted the program seven more times, once in 2016, twice in 2018, twice in 2019, once in 2020, and the special edition Idol Star Championships: Hall of Fame that aired in 2021 in lieu of the usual competition due to COVID-19 pandemic. A week after he hosted his first Idol Star Athletics Championships in 2015, he appeared as the presenter on Mnet's new mystery music game show, I Can See Your Voice alongside Yoo Se-yoon and Kim Bum-soo. Kim left the program after three seasons to focus on his music career and was replaced by singer and entertainer Kim Jong-kook. As of 2021, Leeteuk has hosted all eight seasons of the series. When asked about the secret to the series' longevity, he said that although it "has a mild taste" compared to other entertainment shows, it is "full of charm". In a separate interview, he noted that the show's solid format has allowed it to air for a long time. Since its start, the program has grown into a global franchise, spawning shows in different countries and languages, including the UK and the US versions. • Illustration — Leeteuk during the press conference for Devil in 2015 He appeared as host of several other programs in 2015 like Match Made in Heaven Returns with Lee Hwi-jae, a reboot of 2002 program Kang Ho-dong's Match Made in Heaven, White Swan with Lee Seung-yeon, The Mickey Mouse Club with SM Rookies as the Mouseketeers, and episode 782 of Music Bank, filling in for Park Seo-joon.

He took part in the reality-documentary show Law of the Jungle, filming for Law of The Jungle in Papua New Guinea.

He presented Star Show 360, season 2 of Please Take Care of My Vanity, and Idol Party, as well as participating in the variety show Lucky Race. He was slated to co-host Star Coming, a South Korea-China joint program in late 2016, but its production was abruptly cancelled following rising tensions between the two countries. His roles in the industry earned him the top three spots on the Idol MC of the Year list published by My Daily news portal. The journalist in charge of the list, Lee Seung-gil, praised him for his unique ability to make his guests or his co-hosts to stand out and considered him a "professional MC".

He became a mentor for North Korean and overseas competitors in the reality competition People of Trot beginning in September 2020. In October, he hosted the 2020 Miss Korea beauty pageant, which aired online because of the COVID-19 pandemic in South Korea. Many events were broadcast online instead of being held in public because of social distancing rules implemented during the pandemic, which include the banning of public gatherings. Leeteuk hosted events such as the K-Pop Global Donation Concert World Is One, a charity concert organised by the Munhwa Broadcasting Corporation and World Vision Korea for their COVID-19 pandemic relief fund, the 26th Dream Concert, the 2020 Taekwondo Performance in Seoul, and the DMZ Concert, a part of the 2020 Live in DMZ festival—a peace festival which was held at Imjingak near the Korean Demilitarized Zone (DMZ).

On July 5, 2023, Super Junior-L.S.S., a sub-unit group consisting of Super Junior bandmates Leeteuk, Siwon, and Shindong, debuted with their first Japanese single "Close The Shutter". The trio later made their official Korean debut on January 22, 2024 with the single "Suit Up".

On April 19, 2007, almost two months after Super Junior-T's release of their first single "Rokkugo", Leeteuk was seriously injured in a car accident with Shindong, Eunhyuk, Kyuhyun, and two managers. Returning home after a recording of the radio show Super Junior Kiss the Radio, they were on the highway when the front left tire burst as the driver was switching lanes. The van ran into the guard rail on the driver's side and skidded for about 30 metres. At some point, the momentum caused the van to flip over on its right side. While Shindong and Eunhyuk suffered minor injuries, Leeteuk and Kyuhyun sustained more serious injuries, which required both to be hospitalised. Leeteuk had glass shards embedded in his back and above his eyes, requiring over 170 stitches. He was discharged from the hospital on April 30, 2007. Because of the accident, Leeteuk made only a minor appearance in Super Junior's debut big-screen production, Attack on the Pin-Up Boys in 2007. He was credited as the panda mascot at the end of the film, although it was later confirmed that it had been Ryeowook who portrayed it throughout most of the film.

On January 6, 2014, while Leeteuk was in the military, news broke out that his father, Park Yong-in, and grandparents, Park Hyun-seok and Chun Kyung-tae, were found dead in their home. SM initially released a statement saying that the trio had died in a car accident. It was later revealed it had been a murder-suicide, with Park Yong-in strangling his parents and then hanging himself. A note left near the bodies read, "I will take my parents with me." The news reported that Park had been dealing with depression for a long time. He was also struggling with financial problems on top of having to take care of both his parents who were suffering from dementia. According to the police, Park had planned to admit his parents to a nursing home the next day but changed his mind. They concluded that it is highly likely that Park blamed himself for being unable to continue taking care of his parents. The funeral was held on January 8, with the Super Junior members in attendance. Leeteuk, who was granted emergency leave, resumed his mandatory military service on January 11, 2014, and was discharged on July 29, 2014.

Leeteuk enlisted for his mandatory military service as an active-duty soldier on October 30, 2012, entering the Army's 306th Replacement Battalion in Uijeongbu, Gyeonggi Province. Contemporary reports noted that a 2007 traffic accident had aggravated a pre-existing herniated disc, but that he underwent continued treatment before enlisting. In 2014, Leeteuk stated that he had originally received a supplementary-service classification but chose active-duty service partly because of public scrutiny and his position as the leader of Super Junior. He completed five weeks of basic training at the 9th Infantry Division's recruit training center. During his training, he was selected as the company commander trainee. After completing his training in December, he was assigned to the 1st Infantry Division. In January 2013, Leeteuk appeared in the military musical The Promise, which was jointly produced by the Ministry of National Defense, the Army and the Korea Musical Theatre Association to commemorate the 60th anniversary of the Korean Armistice Agreement. He was subsequently selected to serve in the Ministry of National Defense's public-relations support unit, whose members were commonly known as entertainment soldiers. The Ministry of National Defense abolished the entertainment-soldier system on July 18, 2013, after concluding that repeated controversies had damaged the military's image and public trust. As part of the resulting reassignment of the unit's remaining personnel, Leeteuk's military occupational specialty was changed to rifleman and he was transferred to the 12th Infantry Division on August 2. While serving with the 12th Infantry Division, Leeteuk was granted four nights and five days of bereavement leave following the deaths of his father and paternal grandparents on January 6, 2014. After attending their funeral, he returned to his unit on January 11 and resumed his service. Leeteuk completed 21 months of active-duty service and was discharged from the 12th Infantry Division on July 29, 2014. During an October 2014 appearance on Radio Star, he acknowledged that he had at times regretted choosing active-duty service after experiencing several hardships in succession. He also recalled being transferred to another unit while holding the rank of private first class.
