The men's foil competition in fencing at the 2016 Summer Olympics in Rio de Janeiro was held on 7 August at the Carioca Arena 3.

[2] The event was won by Daniele Garozzo of Italy, the nation's ninth victory in the men's foil (matching France for most all-time) and first since 1996.

The silver medalist was American Alexander Massialas, earning the United States' first medal in the event since 1960.

2008 silver medalist, 2012 top-16 finisher, and reigning world champion Yuki Ota of Japan also returned.

France and the United States each made their 25th appearance, tied for most of any nation; France had missed only the 1904 (with fencers not traveling to St. Louis) and the 1912 (boycotted due to a dispute over rules) foil competitions, while the United States had missed the inaugural 1896 competition and boycotted the 1980 Games altogether.

The 1996 tournament had vastly simplified the competition format into a single-elimination bracket, with a bronze medal match.
