Alexander R. Corbisiero (born 30 August 1988) is an English retired rugby union player who played as a loosehead prop.

[15] In 2008 Corbisiero was a member of the England under-20 team that won the grand slam[16] and reached the final of the 2008 IRB Junior World Championship.

[18][19] Corbisiero made his senior debut for England against Italy on 12 February 2011 after Andrew Sheridan was ruled out of the match with a back injury.

[4] He went on to feature in four of England's five tests as they won the Six Nations Championship, with injury ruling Sheridan out for the rest of the tournament.

In December 2015 (at age 27) Corbisiero announced he would taking a year out from Rugby, saying he was 'mentally drained', but that he envisaged returning to play.

This decision was affected by the attractiveness of continuing his media work with NBC, and his concern about possible injury damage from an extended playing career.

[24] On 27 October 2020, Corbisiero was appointed Scrum Coach for the Los Angeles Giltinis for the 2021 Major League Rugby season.
