The Prairie Fire was a Canadian rugby union team based in Regina, Saskatchewan.

The Prairie Fire were Western Champions for the 2005 and 2006 seasons, but both times came up short in the Super League Final versus the Newfoundland Rock, once in Regina and once in St. John's, Newfoundland, at Swilers Rugby Park.

They won the MacTier Cup at Regina Rugby Park in 2007 defeating the Niagara Thunder, 28–12.

The league is deemed semi-professional because some of the smaller clubs are paying foreign players to play for their side.

The Prairie Fire were chosen as one of the remaining RCSL clubs to enter the newly formed league.
