Sailing at the 2023 Pan American Games – Men's sunfish

The men's sunfish competition of the sailing events at the 2023 Pan American Games in Santiago was held from October 28 to November 4 at the Cofradia Nautica del Pacifico.

Points were assigned based on the finishing position in each race (1 for first, 2 for second, etc.). The points were totaled from the top 9 results of the first 10 races, with lower totals being better. If a sailor was disqualified or did not complete the race, 9 points were assigned for that race (as there were 8 sailors in this competition). The top 5 sailors at that point competed in the final race, with placings counting double for final score. The sailor with the lowest total score won.

Lee Parkhill from Canada won the gold medal after finishing second in the medal race, ahead of his opponents for the title. Jean Paul Valdez from Peru was the runner-up and Diego González from Chile, who entered the medal race fighting for the gold in the regatta, had a poor performance in the last race to win the bronze medal.
