The men's halfpipe competition of the Vancouver 2010 Olympics was held at Cypress Mountain on February 17, 2010.

In each round of competition, each competitor performed two rides through the halfpipe.

In each round (except for the first run of the qualifying round) the order of performance was based on the inverse order of scoring (i.e., the competitor with the lowest score went first and so forth with the highest-scoring competitor going last).

The semifinal round consisted of twelve snowboarders.

In the final round, Shaun White had already wrapped up the gold medal performance with his first run (none of the other competitors' second-run scores exceeded White's 46.8 score), but performed his second run anyway, successfully completing a double McTwist 1260 and improving on his initial score.
