Athletics at the 2008 Summer Olympics were held during the last ten days of the games, from August 15 to August 24, 2008, at the Beijing National Stadium. The Olympic sport of athletics is split into four distinct sets of events: track and field events, road running events, and racewalking events.

The 110 metres hurdles, or 110-metre hurdles, is a hurdling track and field event for men. It is included in the athletics programme at the Summer Olympic Games. The female counterpart is the 100 metres hurdles. As part of a racing event, ten hurdles of 42 inches (106.7 cm) in height are evenly spaced along a straight course of 110 metres. They are positioned so that they will fall over if bumped into by the runner. Fallen hurdles do not carry a fixed time penalty for the runners, but they have a significant pull-over weight which slows down the run. Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks.
