Frank Joseph Zupo (August 29, 1939 – March 25, 2005), nicknamed "Noodles", was an American professional baseball player.

A catcher, he appeared in 16 games over parts of three seasons in Major League Baseball for the Baltimore Orioles in 1957–58 and 1961.

Born in San Francisco, Zupo batted left-handed, threw right-handed, stood 5 feet 11 inches (1.80 m) tall and weighed 182 pounds (83 kg).

He signed with the Orioles for a $50,000 bonus after graduating from Sacred Heart Cathedral Preparatory, a private Roman Catholic high school in his native city.

Recalled after spending that year at three different minor league levels, he appeared in one September game and went hitless in two at bats in relief of the Orioles' regular catcher, Gus Triandos.
