Athletics at the 2007 Summer Universiade – Men's 100 metres

The men's 100 metres event at the 2007 Summer Universiade was held on 10–12 August. The final originally took place on 11 August but the results were cancelled due to a marginal false-start by Simeon Williamson, which was not at first noticed by the officials. A re-run was ordered a day later. The order of medalists, however, stayed the same after the second race.
