Paul Kevin Jonas II, widely known as Kevin Jonas, is an American singer-songwriter, guitarist, and actor who gained prominence as a member of the pop rock band Jonas Brothers. Born on November 5, 1987, in Teaneck, New Jersey, he is recognized for his role as the lead guitarist and an essential figure in shaping the band's musical direction alongside his younger brothers, Joe and Nick Jonas. The Jonas Brothers became cultural icons in the late 2000s, particularly through their association with the Disney Channel, which propelled them into mainstream success.

Kevin's early life was heavily influenced by music, as his father, Paul Kevin Jonas Sr., was a musician and his mother, Denise, encouraged their artistic pursuits. The brothers formed the Jonas Brothers band in 2005, and their breakthrough came with their self-titled debut album released in 2007, which featured the hit single "S.O.S." The band's popularity soared after starring in the Disney Channel's musical television film, Camp Rock, in 2008, and its sequel, Camp Rock 2: The Final Jam, in 2010. They also starred in their own series, Jonas Brothers: Living the Dream, from 2008 to 2010, and Jonas, which aired from 2009 to 2010, allowing fans an intimate look into their lives and careers.

In 2012, the Jonas Brothers announced a hiatus, leading Kevin to pursue other ventures, including starring in his own reality series, Married to Jonas, which followed his life with his wife, Danielle Deleasa, whom he married on December 19, 2009. Following the band's breakup in 2013, Kevin appeared on the seventh season of The Celebrity Apprentice in 2014. He also ventured into business, founding the construction company Jonas Werner and becoming co-CEO of The Blu Market, an influencer marketing company.

After several years apart, the Jonas Brothers made a triumphant return in February 2019, reuniting to release their fifth studio album, Happiness Begins, which featured the hit single "Sucker." The band continued to share their journey through two documentaries on Amazon Prime Video, Jonas Brothers: Chasing Happiness and Happiness Continues, which were released in 2019 and 2020, respectively. Kevin was recognized for his appeal when he was included in People magazine's list of the Sexiest Men Alive in 2008, becoming part of its 21 Club.

In a new chapter of his career, Kevin released his debut solo single, "Changing," on November 20, 2025, showcasing his continued evolution as an artist. Today, he remains an influential figure in the music industry, balancing his roles as a musician, entrepreneur, and family man while continuing to create music with his brothers.
