Ali bin Ahmad (born 1 January 1924) is a Singaporean sprinter and sprinting coach.
In 1940, Ali became the first Singaporean to run the 100 yards in 10 seconds, when still a schoolboy at Victoria School and his name appeared in the Hall of Fame. The timing also equalled the Malayan record.
Ali later became a coach with the Singapore Amateur Athletic Association, coaching Singapore's top sprinters from the 1950s to the 1990s. His proteges include Olympian Kesavan Soon, two-time Olympian C. Kunalan, Tang Ngai Kin, Harun Mundir and Mona Kunalan.
