Nicholas Jerry "Nick" Jonas (born September 16, 1992) is an American singer-songwriter, musician and actor best known as one of the Jonas Brothers, a pop-rock band he formed with his brothers Joe and Kevin. The Jonas Brothers originally started as an attempted solo singing career for Nick, but the record producer liked the sound when his brothers sang backup for him. He previously starred in the Disney Channel original series JONAS L.A. as Nick Lucas, alongside his brothers. He also starred in the Disney Channel original movies Camp Rock and Camp Rock 2: The Final Jam. He formed the band Nick Jonas & The Administration, which released its first album in 2010. He and his brothers recently concluded their tour with the cast of Camp Rock 2: The Final Jam.

Nick Jonas was born in Dallas, Texas, the son of Denise (née Miller), a former sign language teacher and singer, and Paul Kevin Jonas, Sr., a songwriter, musician, and former ordained minister at an Assemblies of God church. He was raised in Wyckoff, New Jersey and homeschooled by his mother. Nick is of Irish (from his maternal grandfather), Cherokee, Italian, and German descent.

He was diagnosed with Type I diabetes at the age of 13 and wears an OmniPod insulin pump to help him manage his condition. He has developed the Change for the Children Foundation. Partnering with five different charities, their goal is to raise money and awareness for diabetes. He also developed a public service announcement with the Washington Nationals to support diabetes care at Children's National Medical Center in Washington, D.C.

Since August 6, 2008, Bayer Diabetes Care has partnered with Jonas as a diabetes ambassador to promote the idea for young people to manage their diabetes. Jonas testified in the U.S. Senate to promote more research funding for the condition.

Miley Cyrus has stated that she dated Jonas from June 2006 to December 2007. Cyrus claimed they were "in love" and began dating soon after they first met.
