The men's pommel horse competition at the 2008 Summer Olympics was held on August 17 at the Beijing National Indoor Stadium. The eight competitors with the highest scores in qualifying proceeded to the men's pommel horse finals. There, each gymnast performed again; the scores from the final round determined the final ranking. There were 76 competitors from 27 nations that competed on the pommel horse, with nations in the team event entering up to 5 gymnasts while other nations could enter up to 2. The event was won by Xiao Qin of China, the nation's second consecutive and third overall victory in the pommel horse. The other two medals went to nations that had never earned a medal in the event before: Filip Ude of Croatia took silver while Louis Smith of Great Britain finished with bronze.

The pommel horse is an artistic gymnastics apparatus. Traditionally, it is used by only male gymnasts. Originally made of a metal frame with a wooden body and a leather cover, the modern pommel horse has a metal body covered with foam rubber and leather, with plastic handles.
