Jack Capuano (born July 7, 1966 in Cranston, Rhode Island) is the head coach of the New York Islanders.

He is a retired former professional ice hockey defenseman who spent parts of three seasons in the National Hockey League in the late 1980s and early 1990s.

A 5th round selection (88th overall) in the 1984 NHL Entry Draft, Capuano played his college hockey at the University of Maine. At Maine, he was a teammate of his younger brother Dave Capuano and played on the same blueline as future NHLers Eric Weinrich and Bob Beers along with future Vancouver Canucks executive Dave Nonis. He enjoyed a decorated college career, earning First-Team All-American honours in his junior year. His 32 goals remains the most ever by a Black Bear.

Capuano turned pro in 1988 following his junior year and signed with the Maple Leafs. He spent his first season with the Newmarket Saints of the AHL recording 21 points in 74 games. He would crack the Leafs' NHL roster for the 1989–90 season, but played in only 1 game before Tom Kurvers returned from a holdout, forcing his demotion. Shortly after his demotion, he walked out on the Saints and demanded a trade, feeling he belonged in the NHL.
