Michael Musyoki (born May 28, 1956), also known by his nickname "Mike", is a retired long-distance runner from Kenya who won the bronze medal in 10,000 metres at the 1984 Summer Olympics.
Musyoki was recruited by University of Texas at El Paso, a school which was building a star-studded team of distance-runners in the late 1970s. Suleiman Nyambui and Musyoki were UTEP's two premier foreign distance-runner recruits at the time, and both of them finished in first and second place respectively in the 10,000 metre race at the 1979 NCAA Outdoor Track Championships.
At the 1978 Commonwealth Games he was silver medalist behind his famous compatriot Henry Rono. At the 1978 All-Africa Games, Musyoki was also 5000 meters silver medalist. In 1982 he broke the half marathon world record by running 61:36 in Philadelphia. He was also an active road racer and won "Road Racer of the Year" award in 1983 by Running Times.
