The men's omnium event at the 2024 Summer Olympics took place on 8 August 2024 at the Vélodrome National de Saint-Quentin-en-Yvelines.

This was the fourth appearance of the event, what has been held at every Summer Olympics since its introduction in 2012.

The entire event is contested within a single day, but there are breaks between each race.

The winner of the omnium is the cyclist who obtains the most points through the four races.

The winner of each of the first three races earns 40 points, the second-place cyclist earns 38, the third-place rider 36, and so forth, and the final race has special scoring rules.
