Upon her retirement from acting in 2010, Bynes publicly struggled with mental health and substance abuse. Her legal problems, which persisted from 2012 to 2014, resulted in her parents being granted conservatorship of her from 2013 to 2022.

Bynes was born on April 3, 1986, and raised in Thousand Oaks, California, a suburb of Los Angeles. Her father is Catholic and is of Irish, Lithuanian, and Polish descent, and her mother is Jewish, born to a Canadian couple whose families were from Poland, Russia, and Romania. Since childhood, Bynes has been interested in illustration and fashion design. In December 2013, Bynes enrolled at the Fashion Institute of Design & Merchandising (FIDM) in Irvine, California for 2014. In 2018, she received her associate's of art degree in merchandise product development and announced her intentions to start a bachelor's degree program. In 2019, Bynes graduated from FIDM.

Bynes began professionally acting at age seven, appearing in television advertisements for Buncha Crunch candies, Cut and Style Barbie, and Taco Bell. During her childhood, she appeared on stage in versions of Annie, The Secret Garden, The Music Man, and The Sound of Music. Later she attended a comedy camp at the Los Angeles Laugh Factory, at which she received advice from Richard Pryor and Arsenio Hall. A Nickelodeon producer spotted her at a performance at the Laugh Factory, which prompted the network to cast her on the sketch comedy series All That, where she played various roles from season three to season six. The show brought Bynes recognition, and she won a Kids' Choice Award in 2000. Bynes was a regular member of the series Figure It Out from 1997 to 1999. At the age of 13, Bynes starred in the All That spin-off comedy The Amanda Show from 1999 to 2002. She had her breakthrough on the show, earning praise and acclaim. She won four Kids' Choice Awards and received two Young Artist Award nominations. In 2002, Bynes made her feature film debut in Big Fat Liar starring as Kaylee, best friend of co-star Frankie Muniz's character. Although the film had a mixed reception, it was a commercial success, and she won another Kids' Choice Award for her performance. Also in 2002, she landed a starring role in the WB sitcom What I Like About You from 2002 to 2006. The series garnered positive reviews and Bynes received a number of nominations from the Teen Choice Awards and the Young Artist Awards. In 2003, Bynes appeared on the cover of Vanity Fair's July 2003 edition. She had a voice role in the direct-to-video film Charlotte's Web 2: Wilbur's Great Adventure, which was panned by critics. She had a voice role as Piper Pinwheeler in the 2005 animated film Robots, which was a commercial success. Also in 2005, she starred in the romantic comedy Love Wrecked.

Bynes was named one of Teen People's "25 Hottest Stars Under 25" in 2006. In 2006, Bynes starred in the teen sports romantic comedy film She's the Man, based on William Shakespeare's Twelfth Night. She portrays Viola Hastings, a girl who pretends to be her twin brother to play with the boys' soccer team at an elite boarding school after the girls soccer team at her school gets cut. Critic Roger Ebert wrote "Of Amanda Bynes let us say that she is sunny and plucky and somehow finds a way to play her impossible role without clearing her throat more than six or eight times. More importantly, we like her." In 2007, Bynes starred as Penny Pingleton, a sheltered young girl, in the musical comedy film Hairspray, based on the musical theater adaptation of John Waters' 1988 film. The film was a critical and commercial success premiering in over 3,000 theaters, the largest debut for any musical film. It went on to become Bynes's most successful film at the time, and she and the rest of the cast were acclaimed for their performances. She won the Critics' Choice Award for Best Acting Ensemble and received a Screen Actors Guild Award nomination in 2008, among others. She was also featured on the Hairspray soundtrack, which received a Grammy nomination. It was announced Bynes would reprise her role in Hairspray 2, but the project was canceled. In August 2007, Bynes worked with Steve & Barry's to create her own fashion line called Dear, consisting of apparel and accessories. The line was cut short when Steve & Barry's filed for bankruptcy in 2008. Bynes' next role was in another comedy, Sydney White, released in 2007. The film was a critical and commercial failure, although Bynes' performance was praised. Review aggregator site Rotten Tomatoes wrote "Amanda Bynes is charming, but Sydney White is a poorly adapted take on Snow White, relying on tired ethnic stereotypes laughs." In 2008, she appeared in the Lifetime Television movie Living Proof as the student assistant of Harry Connick, Jr.'s character. The film and the cast were praised. Also in 2008, Bynes voiced Anna in the Family Guy episode "Long John Peter". In March 2009, Bynes, alongside Tim Peper, Stephanie Lemelin and Baron Vaughn, filmed the ABC pilot Canned, capturing the role of Sarabeth. The workplace comedy followed a group of friends that were all fired on the same day. She was also set to star in the romantic comedy Post Grad, but she dropped out and was replaced by Alexis Bledel amid rumors that she was having difficulties. In January 2010, Bynes posed for the cover of Maxim for their February issue. In June, Bynes announced via Twitter she would retire from acting. The following month, she seemingly retracted her previous statement by tweeting, "i've unretired"; and concurrently posted an advertisement for her upcoming film, Easy A, in which she would co-star alongside then-relatively unknown Emma Stone. She played Marianne Bryant, the president of a high school Bible study club who becomes the personal nemesis of Stone's character. The film was a critical and commercial success, with Stone and Bynes receiving critical praise for their performances. In the same year, Bynes started shooting the Farrelly Brothers comedy film Hall Pass, but dropped out and was replaced by Alexandra Daddario. In a September 2012 interview, Bynes clarified her acting status, telling People, "I am retired as an actor. I am moving to New York to launch my career. I am going to do a fashion line."

In June 2018, Bynes considered returning to acting, but nothing has happened since. In December 2023, Bynes debuted as the co-host of an interview-style podcast, Amanda Bynes & Paul Sieminski: The Podcast, but she left after one episode to "get [her] manicurist license and have a consistent job". In December 2024, she hosted a pop-up art show in West Hollywood, showcasing her collaborative work with fashion designer and artist Austin Babbitt. In April 2026, Bynes signed with Create Music Group, and released her EDM trap single "Girlfriend" featuring Fenix Flexin.

In 2007, Bynes described herself as Jewish and said: "As far as religion, I was raised both. I learned about both [Judaism and Catholicism]. My parents said it was up to me to decide when I grew up. I'm sort of a spiritual person anyway. I haven't decided yet. I don't know yet exactly what I believe." In 2008, Bynes briefly dated Seth MacFarlane after voicing Anna in the episode "Long John Peter" of MacFarlane's show Family Guy. Bynes became engaged to Paul Michael in 2020. In July 2022, E! News reported Bynes and Michael had broken up after two years of dating.

In March 2012, Bynes was pulled over by Los Angeles police for talking on the phone while driving. She then left the scene before the officer could finish writing her ticket. However, he did not pursue her as he already had her information. She later returned to the station to sign the ticket. On April 4, Bynes was arrested for driving under the influence (DUI) in West Hollywood after side-swiping a police car and refusing to take a breathalyzer test. Upon being officially charged in June, Bynes took to Twitter to enlist the help of then-President of the United States Barack Obama after claiming she was wrongfully arrested, writing 'Hey @BarackObama... I don't drink. Please fire the cop who arrested me. I also don't hit and run. The end.' She later accepted a plea bargain of three years probation in exchange for the dismissal of the DUI charge. In May 2013, Bynes was charged with reckless endangerment and marijuana possession after she was found smoking in the lobby of her Manhattan apartment building. When officers entered her 36th-floor apartment, she allegedly threw a bong out the window. A New York County judge dismissed the case against her in June after no evidence of a bong was ever discovered. In July, Ventura County, California, sheriff's deputies detained her after she allegedly started a small fire in the driveway of a stranger in Thousand Oaks. She was hospitalized under a 72-hour mental-health evaluation hold. Bynes's parents filed for conservatorship of their daughter shortly after her July 2013 hospitalization began. In August, Bynes' mother was granted a temporary conservatorship over Bynes's affairs. In October 2014, Bynes accused her father of emotional and sexual abuse in a series of tweets. After her parents protested and claimed innocence, Bynes tweeted that her father had never abused her, adding: "The microchip in my brain made me say those things but he's the one that ordered them to microchip me". Days later, Bynes' mother again received conservatorship of her. Soon afterward, Bynes announced that she had been diagnosed with bipolar disorder. In August 2018, paperwork was filed to continue the conservatorship until August 2020. In 2018, Bynes stated she had been sober for four years with the help of her parents. She apologized for what she said on Twitter during her years of substance use challenges: "I'm really ashamed and embarrassed with the things I said. I can't turn back time but if I could, I would. And I'm so sorry to whoever I hurt and whoever I lied about because it truly eats away at me." In an interview, Bynes stated that during her days of substance use she used cocaine and MDMA, but the drug she "abused the most" was the ADHD prescription medication Adderall. In February 2022, Bynes filed to end her conservatorship. Her attorney stated that Bynes believed her condition was improved and protection of the court was no longer necessary. Attorneys for her parents stated that they supported her in ending it. The conservatorship was officially terminated on March 22, 2022. On March 20, 2023, Bynes was placed on a 72-hour psychiatric hold after she flagged a bystander for help and called 911 following a psychotic episode in Los Angeles. The previous weekend she had been scheduled to appear at an All That panel at '90s Con in Connecticut, her first scheduled public event since the end of her conservatorship, but she did not appear. On June 17, 2023, after she called the police indicating that she had thoughts of self-harm, mental health professionals determined that she needed inpatient treatment. She left the facility on June 30 with plans for follow-up outpatient treatment.
