The Karate Kid Part II is a 1986 American martial arts drama film written by Robert Mark Kamen and directed by John G. Avildsen. It is the second installment in the Karate Kid franchise and the sequel to the 1984 film The Karate Kid, starring Ralph Macchio and Pat Morita. The Karate Kid Part II follows Daniel LaRusso (Macchio), who accompanies his karate teacher Mr. Miyagi (Morita) to see his dying father in Okinawa, only to encounter an old friend-turned-rival with a long-harbored grudge against Miyagi.

Following the success of the first installment, preparation for a sequel began immediately. Upon completion of the final script, Macchio and Morita were re-signed and additional casting took place between May and July 1985. Principal photography began in September in Los Angeles, and filming completed in December. Locations included Oahu, which was used to represent Okinawa in the film.

The Karate Kid Part II was theatrically released in the United States on June 20, 1986. The film received mixed reviews, with critics praising Morita's performance as well as the new location and characters, while others criticized elements of the storyline, the antagonists, and some of the action scenes. The film was a commercial success, grossing $130 million worldwide, making it one of the highest-grossing films of 1986. A sequel titled The Karate Kid Part III was released in 1989.
