The Japan Keirin Autorace Foundation, or JKA Foundation (Japanese: 財団法人JKA, Zaidanhōjin JKA), is the regulating body for pari-mutuel keirin cycle racing and flat track motorcycle racing competitions in Japan. These sports—two of Japan's four authorized "Public Sports" (公営競技, kōei kyōgi) where gambling is permitted—were originally regulated by two separate organizations. These sports and organizations were brought under the authority of the JKA on April 1, 2008.
