The Great Northwest Athletic Conference (GNAC) is a collegiate athletic conference which has historically operated in the northwestern United States, but also currently includes four schools in areas not usually considered part of that region—two in Alaska (neither of which is located in Southeast Alaska, an area often considered part of the Northwest), one in eastern Montana (almost never considered part of the region), and one in the Canadian province of British Columbia (an area included with the Northwest U.S. in the larger Pacific Northwest region).
South Dakota Mines will join the Rocky Mountain Athletic Conference in 2014, but will not move GNAC sports until after affiliation agreements end. The last season for men's soccer will be 2014 and for football will be 2015.

The GNAC didn't sponsor football between the 2006-07 and the 2007-08 seasons. Therefore, Central Washington and Western Washington competed in North Central Conference (NCC); while Dixie State, Humboldt State and Western Oregon were Independents.
