2009–2019 Matthew J. Gilroy (born July 20, 1984) is an American former professional ice hockey defenseman who last played for the SC Rapperswil-Jona Lakers of the National League (NL).

Gilroy played in National Hockey League (NHL) with the New York Rangers, Tampa Bay Lightning, Ottawa Senators and the Florida Panthers.

[2][4] In his senior year, in 2008–09, he was named team captain of the Terriers and recorded a college career-high 36 points in 43 games, first among Hockey East defensemen and third in the NCAA.

[6] The Terriers won in overtime, defeating the RedHawks 4–3, making Gilroy just the fifth player to win the Hobey Baker Award and NCAA championship in the same season.

[9] On October 7, 2012, with the 2012–13 NHL lockout in place, Gilroy was signed to an American Hockey League (AHL) contract with the Connecticut Whale, marking a potential return to the New York Rangers organization.

[11] Gilroy was released to free agency by the Rangers in the off-season and, on July 8, 2013, was signed to a one-year contract with the Florida Panthers, his fourth NHL club.

With limited NHL interest, Gilroy opted to forgo free agency to sign his first European contract on a one-year deal with Russian club Atlant Moscow Oblast of the Kontinental Hockey League (KHL) on June 25, 2014.

Traditional team policy with the Boston University Terriers does not permit players to wear high numbers deemed flamboyant and self-endorsing by head coach Jack Parker.
