The BCS National Championship Game, or BCS National Championship, was a postseason college football bowl game, used to determine a national champion of the NCAA Division I Football Bowl Subdivision (FBS), first played in the 1998 college football season as one of four designated bowl games, and beginning in the 2006 season as a standalone event rotated among the host sites of the aforementioned bowls.

In North America, a bowl game, or simply bowl, is one of a number of postseason college football games that are primarily played by teams belonging to the NCAA's Division I Football Bowl Subdivision (FBS). For most of its history, the Division I Bowl Subdivision had avoided using a playoff tournament to determine an annual national champion, which was instead traditionally determined by a vote of sports writers and other non-players. In place of such a playoff, various cities across the United States developed their own regional festivals featuring postseason college football games. Prior to 2002, bowl game statistics were not included in players' career totals. Despite attempts to establish a permanent system to determine the FBS national champion on the field, various bowl games continue to be held because of the vested economic interests entrenched in them.
