Nicholas Jerry "Nick" Jonas (born September 16, 1992) is an American singer-songwriter 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 currently stars in the Disney channel original series JONAS as Nick Lucas, alongside his brothers.

Jonas was born in Dallas, Texas, 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 was raised in Wyckoff, New Jersey and homeschooled by his mother.

He was diagnosed with Type I diabetes at the age of 13 and wears an OmniPod insulin pump to help him manage his diabetes. 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.
