Clifford Roland Dapper (January 2, 1920 – February 8, 2011) was a Major League Baseball catcher who played for the Brooklyn Dodgers during the 1942 season. Listed at 6 ft 2 in (1.88 m), 190 pounds (86 kg), he batted and threw right-handed.

Born in Los Angeles, Dapper began his baseball career at age 18 for the Class-B Bellingham Chinooks in the Western International League. With many players unavailable due to World War II, Dapper got his shot at the majors in April 1942, appearing in eight games for Brooklyn. He recorded eight hits in 17 at-bats for a .471 batting average, including a home run, one double, two runs and nine RBI. Despite his hot hitting, Dapper was unable to dislodge all-star Mickey Owen from the catcher's position for the Dodgers, and he was returned to the minors. Later that season he was drafted into the US Navy, and missed the 1943–45 seasons while serving in the South Pacific during World War II.

Following his military discharge, Dapper returned to baseball as a player and then manager, helming Pittsburgh Pirates farm clubs in Eugene, Oregon, and Billings, Montana, all while still an active player. He eventually played 1,623 minor-league games over a twenty-year span, hitting .274 and 102 homers before retiring in 1957, the same year that his former team, the Brooklyn Dodgers, moved to his home town of Los Angeles.
