The men's Keirin event at the 2024 Summer Olympics took place on 10 and 11 August 2024 at the Vélodrome National de Saint-Quentin-en-Yvelines.

This was the 7th appearance of the event, which has been held at every Summer Olympics since its introduction in 2000.

The cyclists follow a pace motorcycle for 3 laps (750 m); the motorcycle then pulls away and the cyclists race for another 3 laps.

These distances are changed from the 2016 Games, shortening the paced section from 5.5 laps and lengthening the unpaced sprint from 2.5 laps.

The motorcycle starts at 30 km/h and increases speed to 50 km/h before it pulls off.
