Brian David Crouser (born August 9, 1962) is a retired javelin thrower from the United States, who twice (1988 and 1992) competed at the Summer Olympics during his career.

He immediately became interested in the throwing events, practicing the shot, discus, and javelin, in his backyard in a quiet, suburban, neighborhood in Gresham, Oregon.

In 1981, while attending Gresham, Brian became the first boy to win the state championship in all three throwing events (Shot-put, Javelin, and Discus).

Crouser, during his stay at Bess Kaiser Hospital, with the eternal love of throwing, was often seen practicing his steps and crossovers in the halls.

His nephew Ryan Crouser is a three time Olympic Gold medalist and is the current world record holder in the shot put.
