Acting
Jonas's career started when he was discovered at the age of 6 in a barber shop while his mother was getting her hair cut and was referred to a professional show business manager. At the age of 7, he began performing on Broadway. He had acted in several plays, including A Christmas Carol (in 2000 as Tiny Tim and Scrooge at eight), Annie Get Your Gun (in 2001 as Little Jake), Beauty and the Beast (in 2002 as Chip), and Les Misérables (in 2003 as Gavroche). After Les Misérables closed, he performed in The Sound of Music (as Kurt) at the Paper Mill Playhouse.

On June 21, 2010 Jonas made his West End debut performing in Les Misérables for the second time, but this time as the role of Marius Pontmercy. Jonas was originally supposed to play the role for only three weeks, but was able to extend his run until July 24, 2010 because of changes in the Jonas Brothers tour schedule. He also appeared in the 25th Anniversary Concert at The 02 Arena on October 3, 2010, again playing the role of Marius Pontmercy.

On August 17, 2007, Jonas, along with his brothers, guest starred in an episode of Hannah Montana, which aired after the premiere of High School Musical 2 and the Disney Channel show Phineas and Ferb. The episode broke basic cable records with a record 10.7 million viewers and became basic cable's most watched series telecast ever.

Jonas and his brothers filmed a Disney Channel Original Movie called Camp Rock where they play a band called "Connect Three." Joe plays the lead male role and lead singer "Shane Gray"; Nick plays the role of "Nate," a guitarist; and Kevin plays the role of "Jason," also a guitarist. A soundtrack for the movie was released on June 17, 2008. The movie premiered on June 20, 2008 in the USA on Disney Channel, and Canada on Family. Production began on the sequel, Camp Rock 2: The Final Jam in September 2009 and is set to premiere during the summer of 2010.

The reality short series, Jonas Brothers: Living the Dream, premiered on Disney Channel on May 16, 2008. The show, which ran until September 5, 2008, documents the brothers' lives on the Look Me In The Eyes Tour. The name was inspired by the band's hit song "When You Look Me in the Eyes". The series was renewed for a second season, which premiered on March 21, 2010. The second season follows the band on the European leg of their World Tour 2009.

Jonas and his brothers previously starred in the Disney Channel Original Series JONAS about a pop band trying to live a normal life, which premiered May 2, 2009 and concluded on March 14, 2010. Filming for the second season began in February 2010. The second season was renamed Jonas L.A., and premiered on June 20, 2010. On November 8, 2010, it was announced that the series had been cancelled.

Jonas will appear in the 2010 series Mr. Sunshine; he will play Eli White, an up-and-coming singer who wants everything his way before he performs at the Sunshine Center.

Going Solo
In 2002 while performing in Beauty and the Beast, Nick had written a song with his father called "Joy to the World (A Christmas Prayer)." With background vocals from the Beauty and the Beast cast, Nick performed the song on the 2002 annual Broadway "Equity Fights AIDS" album, Broadway's Greatest Gifts: Carols for a Cure, Vol. 4. In November 2003, INO Records received a demo copy of "Joy To The World (A Christmas Prayer)." The label released the song to Christian radio, where it quickly became popular on Record & Radio's Christian Adult Contemporary Chart. While Nick was working on his solo project, Joe followed in his footsteps to Broadway, appearing in Baz Luhrmann's production of La Boheme.

By September 2004, an executive at Columbia Records found out about Nick's song. Nick was soon jointly signed to INO Records and Columbia Records and released the single "Dear God". A second single, "Joy to the World (A Christmas Prayer)" (a new solo recording), was released on November 16. It was supposed to be followed by a December release of a self-titled solo album Nicholas Jonas, but the album was pushed back. It did, however, get a limited release. Nick, along with Kevin and Joe, had written several other songs for the album.

In early 2005, Columbia Records' new president, Steve Greenberg, listened to Nick's record. While Greenberg did not like the album, he did like Nick's voice.

Nick Jonas is currently working on a side project from the Jonas Brothers called "Nick Jonas and the Administration". Their debut album Who I Am was released February 2, 2010. The band members consist of Tommy Barbarella on keyboard, Michael Bland on drums, John Fields on bass, and David Ryan Harris on guitar. Although David Ryan Harris recorded guitar in the studio for Who I Am he was unable to go on tour with the rest of band and was ultimately replaced by Sonny Thompson.

In January 2010 Jonas embarked on the Who I Am Tour with the Administration. This was Jonas' first tour without his brothers. The tour consisted of 22 dates that began on January 2, 2010 in Dallas, Texas and concluded on January 30, 2010 in Berkeley, California.
