Jack C. Capuano Jr. (born July 7, 1966) is an American ice hockey coach and former player.

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 Toronto Maple Leafs General Manager, Dave Nonis.

He enjoyed a decorated college career, earning First-Team All-American honors in his junior year.

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.

Capuano would have his finest professional season in 1990–91, recording 20 goals and 50 points and earning 2nd-team All-Star honors in the IHL playing for the Milwaukee Admirals, Vancouver's minor-pro affiliate.

The following season, 2006–07, Capuano became an assistant coach for the Islanders' AHL affiliate, the Bridgeport Sound Tigers.

On April 27, 2016, Capuano was hit by a puck during a playoff game between the New York Islanders and Tampa Bay Lightning.
