Ralph Arthur "Babe" Pinelli, born Rinaldo Angelo Paolinelli was a third baseman and umpire in Major League Baseball. Born in San Francisco, his playing career was mostly with the Cincinnati Reds from 1922 to 1927. He also played with the Chicago White Sox (1918) and Detroit Tigers (1920).

After that he became a highly regarded National League umpire from 1935 to 1956, officiating in 6 World Series: 1939, 1941, 1947, 1948 (outfield only), 1952 and 1956; he was crew chief for the final two Series. He also umpired in the All-Star game in 1937, 1941, 1950 and 1956, working behind home plate for the second half of the last three games, and he worked in the 3-game series to determine the NL champion in 1946.

Pinelli wrote an article for The Second Fireside Book of Baseball, titled "Kill the Umpire? Don't Make Me Laugh!" in which he told about his rookie year of 1935, when he was told that he should not call a strike on Babe Ruth, who was winding up his career with the Boston Braves. Pinelli did not see it that way.

When he was behind the plate and Ruth came to bat, and a close pitch went by at which Ruth did not swing, Babe deemed it a strike and so called it. Ruth turned to the umpire and bellowed, "There's forty thousand people in this park that know that was a ball, tomato-head!" Pinelli did not lose his cool. He replied calmly, "Perhaps—but mine is the only opinion that counts." Ruth had no answer for that.

His final game as a home plate umpire provided an extraordinary capstone to his career. He was behind the plate for Don Larsen's perfect Game 5 in the 1956 World Series. His final call as a plate ump presumably was "Strike 3! You're out!" to pinch-hitter Dale Mitchell. Pinelli later recalled that after the game, he returned to the umpires' room and burst into tears. It has often been reported that that was Pinelli's final game as an umpire, but that is incorrect; Pinelli was a field umpire for the final two games of the Series, and then called it a career.

He was elected to the National Italian American Sports Hall of Fame in 2000.
