() is an arcade fighting game developed by Konami. It first had a limited Japanese release in October 1984, before having a wide release nationwide in January 1985 and then internationally in March 1985. Along with Karate Champ (1984), which influenced Yie-Ar Kung Fu, it is one of the games that established the basis for modern fighting games. The game was inspired by Bruce Lee's Hong Kong martial arts films, with the main player character Oolong modelled after Lee (like Bruceploitation films). In contrast to the grounded realism of Karate Champ, Yie Ar Kung-Fu moved the genre towards more fantastical, fast-paced action, with various different characters having a variety of special moves and high jumps, establishing the template for subsequent fighting games. It also introduced the health meter system to the genre, in contrast to the point-scoring system of Karate Champ. The game was a commercial success in arcades, becoming the highest-grossing arcade conversion kit of 1985 in the United States while also being successful in Japan and Europe. It was ported to various home systems, including home computer conversions which were critically and commercially successful, becoming the best-selling home video game of 1986 in the United Kingdom.

On his side is a variety of punch and kick blows reachable by combining the joystick with one of the buttons (punch or kick). He also has the greatest jumping ability of all the game's fighters, with the exception of "Blues". The player faces a variety of opponents, each with a unique appearance and fighting style. The player can perform up to 16 different moves, using a combination of buttons and joystick movements while standing, crouching or jumping. Moves are thrown at high, middle, and low levels. Regardless of the move that defeated them, male characters (save Feedle) always fall unconscious lying on their backs with their legs apart (Oolong flails his legs), and female characters always fall lying on their sides. Feedle disappears. When a player gains an extra life, the
