Joseph Adam "Joe" Jonas is an American musician and actor. He was born in Casa Grande, Arizona, the son of Denise, a former sign language teacher and singer, and Paul Kevin Jonas Sr., a songwriter, musician and former ordained minister at a Pentecostal Assemblies of God church. He is of Italian, Irish, German, and Cherokee Indian descent. The Jonases are known for their wholesome, "family-friendly" image, and the brothers are all committed Evangelical Christians. They were home-schooled by their mother. In addition, to signify their vow to abstain from premarital sex, on their left-hand ring finger they all wear purity rings. Joe has said that the rings symbolize "a promise to ourselves and to God that we'll stay pure till marriage," and Nick had stated that "it's purity rings pretty awesome, and the rings are just one of our ways of kind of like being different than everybody else out there." They reportedly also abstain from alcohol, tobacco, and drugs.

On August 17, 2007, Joe, along with his brothers, guest starred in an episode of Hannah Montana. The episode debuted alongside High School Musical 2 and a sneak peek of the new 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.

Joe 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. The film's soundtrack was released on June 17, 2008.

The Disney Channel reality short series, Jonas Brothers Living the Dream, premiered on Disney Channel on May 16, 2008. The show, which ran until September 5, 2008, documented 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".

Joe, along with his three brothers Kevin, Nick and Frankie will also be starring in their own Disney Channel Original Series, entitled JONAS, which they are currently filming.

In 2006, Joe Jonas dated AJ Michalka of pop-duo Aly & AJ, as confirmed by Michalka on her MySpace blog.

In 2008, Joe was in a high-profile relationship with country pop singer Taylor Swift On November 11, 2008, in an interview on The Ellen DeGeneres Show, Swift claimed that Joe broke up with her in a 27-second phone call. In explanation, Joe wrote on his MySpace blog (in a post that has since been removed): "I called to discuss feelings with the other person, and obviously these feelings were not well received. I did not end the phone call. Someone else ended it for me. Phone calls only last as long as the person on the other end is willing to talk." Furthermore, Joe says that he has tried to call her since the breakup, in an attempt at reconciliation, but received no response. During the same interview with Ellen DeGeneres, Swift revealed that the heartbreak song "Forever & Always" on her album Fearless, recorded in late September/early October 2008, was inspired by Joe Jonas.
