Adam Noah Levine is an American singer-songwriter and musician, best known as the front man and guitarist for the pop rock band Maroon 5. He is also a coach on the American talent show The Voice.

Levine was born in Los Angeles, the son of Patsy Noah and Fred Levine. His uncle is journalist and author Timothy Noah. He has a brother, Michael, and a sister, Julia Milne.When he was six, he made the winning shot of his local YMCA championship basketball game (on a team his father coached) with no time left on the clock. He has said that the incident changed his life and gave him the confidence to be successful.

Levine attended French Woods Festival of the Performing Arts Camp (Hancock, NY) with best friend Jesse Carmichael, guitar player of the band known at that time as Kara's Flowers. He graduated from Brentwood School in 1997.

Levine has Jewish ancestry on both sides of his family (his father and maternal grandfather were Jewish), and considers himself Jewish, though according to The Jewish Chronicle, who interviewed Levine, he "has rejected formal religious practice for a more generalized, spiritual way of life". As a child, when asked by his father whether he wanted a bar mitzvah, Levine said no.

Having met at Brentwood School in Los Angeles, the band released their first album entitled The Fourth World in 1997 as high school seniors. That same year the band appeared on an episode of Beverly Hills, 90210. The album had little success, and its only single, "Soap Disco", failed commercially. Disappointed with the results of their album, the band members went their separate ways.

Levine and Carmichael left Los Angeles for New York. This was the first time the two Los Angeles natives were exposed to a completely different music scene, a cultural awakening for the young men. On MTV News, in 2002, Levine said, "That's when I started waking up to the whole hip hop, R&B thing. We had friends named Chaos and shit. It was not Brentwood High."

During this time, Levine worked a two-week stint as a waiter at Johnny Rockets. After dropping out of Five Towns College, Levine and Jesse reunited with Mickey and Ryan, but added former Square guitarist, James Valentine in 2001. Renaming the band Maroon 5, Levine and his friends began to compile all of their new found musical influences into their music. While Levine was working as a writer's assistant on the television show "Judging Amy," he spent time writing the lyrics about his ex-girlfriend, Jane. Those lyrics became the album "Songs About Jane."

Levine has collaborated with various musical acts. In 2005, Levine was featured on the Ying Yang Twins song "Live Again". He appeared on Kanye West's Late Registration album, on the third single, "Heard 'Em Say". He is also featured in the song "Wild Horses" on Alicia Keys' third album Alicia Keys: MTV Unplugged. Over the next year, he co-wrote the track "Say It Again" on Natasha Bedingfield's album N.B.. He also performed the background vocals on this song. Most recently, Levine offered his vocals on Gym Class Heroes' newest album in the song "Stereo Hearts".

Levine has made four notable comic appearances on television. During 2007, he appeared on the 33rd season premiere of Saturday Night Live in an SNL Digital Short called Iran So Far with Andy Samberg, Fred Armisen and Jake Gyllenhaal. Levine played himself while singing a humorous bridge to a "love song" for Mahmoud Ahmadinejad. In 2008, he appeared on Comedy Central's "Night Of Too Many Stars". Levine also had a cameo on Jimmy Kimmel Live for the night of stars and endorsed Barack Obama in the 2008 Presidential Election.

In October 2008, Levine collaborated with First Act to create the First Act 222 Guitar, fashioned to Levine's specifications. The guitar was made available for purchase at Target retail stores.

Levine has stated in various interviews that he does not plan on continuing in Maroon 5 forever, and may stop after the tour for Maroon 5's third album.

Levine made a guest appearance as himself on the season three finale of 30 Rock in the episode Kidney Now!.

In 2009, Levine recorded "Gotten", a song for Slash's first solo album Slash released in April 2010. "Gotten" was premiered at amazon.com on March 29, 2010.

Levine is also featured as a singer for his band's song "She Will be Loved" in the music rhythm game Band Hero.

In February 2010, he was among approximately 80 musicians who sang on the charity-single remake of "We Are the World" called "We Are the World 25 for Haiti".

Levine is one of the contestant judges and coach mentors on the singing TV show, The Voice. The winner, Javier Colon, was on Levine's team.

Levine's ex-girlfriend Jane is the muse behind the name of the band's debut album Songs About Jane. In a 2004 interview, he claimed that she had not contacted him despite the success of the album. They have since made up, and by 2007, Levine referred to them as being "close friends".

Levine is a "car junkie", his favorite car being his 1971 Mercedes 280 SE 3.5 Cabriolet.

In 2006, Levine broke his sternum while lifting weights, what he called "one of the most painful things I’ve ever experienced." He began using spotters while lifting weights before giving up weightlifting completely when he began yoga in 2007.

In September 2010, Levine said on the Howard Stern Show he had been dating Russian Sports Illustrated swimsuit and Victoria's Secret model Anne Vyalitsyna seriously for about eight months. The couple met when Maroon 5 performed at the 2010 Sports Illustrated Swimsuit Issue release party in Las Vegas.
