The men's épée was a fencing event held as part of the Fencing at the 1912 Summer Olympics programme. It was the fourth appearance of the event, which had been introduced in 1900. The competition was held from 11 to 13 July at the Östermalm Athletic Grounds. There were 93 competitors from 15 nations. Each nation could enter up to 12 fencers. The event was won by Paul Anspach of Belgium. His countryman Philippe le Hardy took bronze. Silver went to Denmark's Ivan Joseph Martin Osiier, the only medal won by the perennial Olympian who competed in seven Games over 40 years. The medals were the first in the men's épée for both nations.

Belgium competed at the 1912 Summer Olympics in Stockholm, Sweden.
