The men's long jump event at the 1976 Summer Olympics in Montreal, Quebec, Canada, had an entry list of 33 competitors from 25 nations, with two qualifying groups (33 jumpers) before the final (12) took place on Thursday July 29, 1976.

[1] The event was won by 24cm by Arnie Robinson of the United States, the nation's third consecutive and 16th overall gold medal in the men's long jump.

Randy Williams took silver, but the chance of an American sweep (which had happened twice long before in 1896 and 1904) was eliminated when Larry Myricks broke his foot warming up for the final.

[2] Antigua and Barbuda, Fiji, the Ivory Coast, Lebanon, and Trinidad and Tobago each made their first appearance in the event.

The qualifying round gave each competitor three jumps to achieve a distance of 7.80 metres; if fewer than 12 men did so, the top 12 (including all those tied) would advance.
