Steven Richard Nicosia (born August 6, 1955) is a Major League Baseball catcher from 1978 through 1985 for the Pittsburgh Pirates, San Francisco Giants, Montreal Expos and Toronto Blue Jays. The 1973 first round draft pick was a member of the 1979 world champion Pittsburgh Pirates team.

Steve was born in Paterson, New Jersey. At the age of only twenty-two, he made his major league debut for the Pirates on July 8, 1978. Although Nicosia was primarily a platoon catcher (starting against left-handed pitchers), he was called on to start at catcher for four of the seven games in the 1979 World Series against the lefty-heavy starting rotation of the Baltimore Orioles. Steve was behind the plate for the Pirates World Series winning Game Seven victory over the Orioles.

Interestingly, during highlights of Game Seven of the 1979 World Series, Nicosia can be seen delivering several punches to a fan (00:05:00) who tried to take his catcher's mask following the conclusion of the game. The fan was one of hundreds who had invaded the playing surface of Baltimore's Memorial Stadium trying to secure souvenirs of the victory.
