The men's coxless four (M4-) competition at the 1984 Summer Olympics took place at Lake Casitas in Ventura County, California, United States.

It was held from 31 July to 5 August and the outcome was wide open due to the Eastern Bloc boycott and thus the absence of the dominating team from the Soviet Union, and previously East Germany.
