Michael Joseph Piazza is an American former Major League Baseball catcher. He played in his career with the Los Angeles Dodgers, Florida Marlins, New York Mets, San Diego Padres and the Oakland Athletics.

A 12-time All-Star, Piazza is often regarded as one of the best-hitting catchers of all time and holds the record for home runs hit by a catcher, with a career total of 427. He had at least one RBI in 15 consecutive games for the New York Mets in 2000, the second-longest RBI streak ever (Ray Grimes of the Chicago Cubs had 17 consecutive games in 1922).
