2008–09 Celtic League
The 2008–09 Celtic League (known as the 2008–09 Magners League for sponsorship reasons) was the eighth Celtic League season and the third with Magners as title sponsor. The season began in September 2008 and ended in May 2009. Ten teams played each other on a home-and-away basis, with teams earning four points for a win, and a bonus point for scoring four or more tries in a match. Losing teams also earned a bonus point if they lost by seven points or less.
