Kenneth Joseph Silvestri (May 3, 1916 – March 31, 1992) was an American professional baseball player, coach and manager. During his 16-year playing career, he was a backup catcher in the Major Leagues over eight seasons scattered between 1939 through 1951, appearing for the Chicago White Sox (1939–40), New York Yankees (1941; 1946–47) and Philadelphia Phillies (1950–51).

Silvestri was born in Chicago and attended Purdue University. A switch-hitter who threw right-handed, he stood 6 feet 1 inch (1.85 m) tall and weighed 200 pounds (91 kg). He served in the United States Army during World War II.

As a big leaguer, Silvestri batted .217, with 44 hits, 11 doubles, one triple, five home runs and 25 RBI in 102 games played. As a member of the 1950 Phillies, he appeared in Game 2 of the 1950 World Series as a defensive replacement, spelling starting catcher Andy Seminick and handling Baseball Hall of Famer Robin Roberts for two scoreless innings. However, the opposing Yankees broke through to win the game after Silvestri was removed for a pinch hitter in the ninth.
