Cobra Kai is an American martial arts comedy drama television series created by Josh Heald, Jon Hurwitz, and Hayden Schlossberg, and distributed by Sony Pictures Television. It serves as a sequel to the first three The Karate Kid films created by Robert Mark Kamen. Cobra Kai premiered on May 2, 2018 and concluded on February 13, 2025, after six seasons consisting of 65 episodes. Originally released on YouTube Red / YouTube Premium for its first two seasons, the series later moved to Netflix.
