Paul Kevin Jonas Jr. (born November 5, 1987) is an American musician and actor. He rose to fame as the lead guitarist of the pop rock band Jonas Brothers alongside his younger brothers Joe and Nick. Jonas became a prominent figure on the Disney Channel alongside his brothers in the late 2000s, gaining a large following through the network: he appeared in the widely successful musical television film, Camp Rock (2008) and its sequel, Camp Rock 2: The Final Jam (2010) as well as two other series, Jonas Brothers: Living the Dream (2008–2010) and Jonas (2009–2010).

After the group confirmed a hiatus in 2012, Kevin appeared on his own E! reality series, Married to Jonas, with his wife, Danielle. Following the band's initial break-up in 2013, Jonas appeared on the seventh season of The Celebrity Apprentice in 2014, founded the construction company Jonas Werner, and became the co-CEO of The Blu Market, an influencer marketing company. In 2019, he rejoined the Jonas Brothers following their reunion. The group would go on to release their fifth studio album. The reunited Jonas Brothers appeared in two Amazon Prime Video documentaries named Jonas Brothers: Chasing Happiness and Jonas Brothers: Happiness Continues in 2019 and 2020.

Jonas appeared on People magazine's list of the Sexiest Men Alive in 2008 at 21 and was thus included as part of the 21 Club.
