Mervyn John Shea (September 5, 1900 – January 27, 1953) was an American professional baseball catcher and coach. He played in Major League Baseball (MLB) for the Detroit Tigers, Boston Red Sox, St. Louis Browns, Chicago White Sox, Brooklyn Dodgers, and Philadelphia Phillies between 1927 and 1944. Born in San Francisco to Irish immigrants, at age five he survived the deadly 1906 San Francisco Earthquake, although the Shea family home was demolished in the temblor.
