Robert George Deer (born September 29, 1960 in Orange, California) is a former U.S. baseball player. He attended Canyon High School in Anaheim and Fresno City College, and was drafted by the San Francisco Giants in the 4th round of the 1978 amateur draft.
Deer is famous for hitting the game-tying home run on Easter Sunday in 1987, to give the Milwaukee Brewers their 12th straight win to start the season. The home run was featured on the cover of Sports Illustrated. He also carries the dubious honor of having the lowest official batting average while still qualifying for the batting title when he batted .179 in 1991. He is the only player since 1910 to have a batting average less than .220 in at least 400 at-bats in at least four seasons.
A notorious free swinger, Deer held the American League record for strikeouts in a season (186 strikeouts in 1987) until being passed by Jack Cust in 2008, and had at least 140 strikeouts on seven occasions.
Deer currently serves as a roving hitting instructor for the San Diego Padres minor league system.
