The 2009 County Championship season, known as the LVCounty Championship for sponsorship reasons, was the 110th County Championship season. It was contested through two divisions: Division One and Division Two. Each team played all the others in their division both home and away. The top two teams from Division Two were promoted to the first division for the 2010 season, while the bottom two sides from Division 1 were relegated.
