The men's Laser class sailing event at the 2011 Pan American Games will be held from October 17–23 at the Vallarta Yacht Club in Puerto Vallarta.

[1] The defending Pan American Games champion is Andrew Campbell of the United States.

Points were assigned based on the finishing position in each race (1 for first, 2 for second, etc.).

Each boat can drop its lowest result provided that all ten races are completed.

If a boat does not enter a race (DNE) they are given 14 points, and this score must count towards their net total.
