Robert "Bob" Zupcic (born August 18, 1966 in Pittsburgh, Pennsylvania) is a former outfielder in Major League Baseball who played for the Boston Red Sox (1991–1994) and Chicago White Sox (1994). He batted and threw right-handed.

In a four-season career, Zupcic posted a .250 batting average with seven HR and 80 RBI in 319 games played. Despite only hitting seven home runs in his career, Zupcic's greatest accomplishment may have been hitting two grand slams during his rookie season of 1992. The only other Red Sox players to have accomplished this feat are Ellis Burks and Ryan Kalish (in 1987 and 2010 respectively).

Alphabetically, Zupcic appears last on the all-time list of Boston Red Sox players. For the Chicago White Sox, only 1910 outfielder Dutch Zwilling appears after Zupcic.

Zupcic attended Bishop Egan (now Conwell-Egan) High School in Fairless Hills, Pennsylvania and Oral Roberts University. In 1985, Zupcic was awarded Baseball America's Summer Player of the Year Award after playing for the Liberal BeeJays in the Jayhawk League, a summer collegiate league in Kansas and Missouri.^{[citation needed]}
