Chad was represented by one male athlete at the 2016 Games in athletics – Bachir Mahamat in the 400 metres. Mahamat competed on 12 August in the second heat. He placed seventh, with a time of 48.59 seconds, some 3.44 seconds behind the winner, Bralon Taplin of Grenada. The only runner he placed ahead of in his heat was Anas Beshr of Egypt, who had been disqualified for exiting his lane on the track. Only the first three athletes from each heat progressed to the next round, and so Mahamat's Olympics ended after that single run. His time placed him in 48th place out of 50 athletes overall, based on times in the first round.
