Joseph Keter (born 13 June 1969) is a former Kenyan athlete, winner of 3000 m steeplechase at the 1996 Summer Olympics.

Born in Lessos, Nandi District, Joseph Keter, an officer of Kenyan Army, had only one good season throughout his athletics career, which culminated with an Olympic gold medal.

In Atlanta, the hot favourite to 3000 m steeplechase gold medal was a world record holder Moses Kiptanui.

But in the Olympic final, Kiptanui was strongly challenged by his Armed Forces' colleague Keter.

After the Olympic Games, Keter beat Kiptanui again in Zürich, running his personal best 8.05.99.
