The men's trap event at the 2008 Summer Olympics took place on August 9 and 10 at the Beijing Shooting Range Clay Target Field.

Defending Olympic champion Aleksei Alipov of Russia took bronze this year, making him the fifth man to earn two medals in the trap.

Two-time (1996 and 2000) gold medalist Michael Diamond of Australia, who had finished 8th in 2004 and missed the cut for the finals, also returned; so did 2000 finalist David Kostelecký, who had not competed in 2004.

To compete, a shooter needed a quota spot and to achieve a Minimum Qualification Score (MQS).

There was no final-round Olympic record due to the rule change limiting competitors to one shot per target in the final round.

David Kostelecký set the initial Olympic record for the new final total, hitting 146 targets.
