The Senior men's race at the 2010 IAAF World Cross Country Championships was held at the Myślęcinek Park in Bydgoszcz, Poland, on March 28, 2010.

Updates were made to the original rankings of the senior men's race due to doping disqualifications of two Moroccan athletes.

[10] †: Chakir Boujattaoui of Morocco was the original 12th-place finisher in 33:42 min, but was disqualified for a doping offence.

[11] His teammate Ahmed Baday, originally 29th before Boujattaoui's ban, was later disqualified for doping as well, which resulted in the removal of Morocco from the team rankings as it failed to have four valid finishers.

[12] According to an unofficial count, 135 athletes from 39 countries participated in the senior men's race.
