Steven "Big Mac" MacIntyre (born August 8, 1980) is a Canadian former professional ice hockey left winger, who last played for the Carolina Thunderbirds in the FPHL, and is known as an enforcer.

MacIntyre came to the Continental Elite Hockey League (CEHL) in 2001, after earning the reputation as one of Canada's best fighters in Major Junior circles.

MacIntyre led the CEHL in penalty minutes and received a lifetime ban late in the season for his part in a nasty brawl with the Detroit Lightning.

He would spend the next two years within the Rangers' minor league affiliates, the Hartford Wolf Pack and the Charlotte Checkers, before having brief stints playing for the Quad City Mallards and the Providence Bruins, in 2006–07 and 2007–08, respectively.

On November 11, 2008, the Oilers placed MacIntyre on their Injured Reserve (IR) list, with a fractured orbital bone, an injury he sustained from a fight five nights earlier, against the Pittsburgh Penguins with fellow NHL "heavyweight" Eric Godard.

On November 9, 2009, he was assigned to the Oilers' minor league affiliate, the Springfield Falcons on waivers, after playing bit parts in 4 games.
