Teh Kew San (郑求山) (born 1934) is a former Malaysian badminton player who won national and international titles from the late 1950s to the mid-1960s. An "all-rounder" (player competitive in all three events: singles, doubles, and mixed doubles), his greatest successes came in men's doubles with Lim Say Hup. They won a number of major international tournaments on three continents, most notably the prestigious All-England title in 1959. Kew San's singles titles included the Mexico City International in 1960 and the Asian Championship in 1962. Known for his agility and deft racket work, he was a member of four consecutive Malayan/Malaysian Thomas Cup teams (1958, 1961, 1964, 1967), captaining the last which captured the world team title.
