The 2004 County Championship season, known as the Frizzell County Championship for sponsorship reasons, was contested through two divisions: Division One and Division Two. Each team plays all the others in their division both home and away. The top three teams from Division Two were promoted to the first division for 2005, while the bottom three sides from Division 1 are relegated.
