Foo Kok Keong (born 8 January 1963 in Gombak, Selangor) is a former badminton star from Malaysia who rated among the world's best singles players from the late 1980s to the mid-1990s. Not a stylish looking player, he was noted for his quickness, stamina, and never-say-die tenacity. Kok Keong played for the Malaysian Thomas Cup (men's international) team which finished second to China in 1990, and for the team which defeated Indonesia for the world championship in 1992. His victories in individual competition included the Singapore Open and French Open singles titles in 1990, and the Asian Championships singles title in 1994. He was a runner-up in the Malaysia Open (1990, 1991), the British Commonwealth Games (1990), the World Grand Prix Final (1989), and the All-England Championships (1991).
In 1991, Foo Kok Keong became the first Malaysian to reach the number 1 world ranking since the ranking system is implemented by the International Badminton Federation (IBF) in the 80's.
