The 2007–08 Celtic League (known as the 2007–08 Magners League for sponsorship reasons) was the seventh Celtic League season and the second with Magners as title sponsor. The season began on 31 August 2007 and finished on the weekend beginning 10 May 2008. Some disruption to fixtures occurred as a result of the 2007 Rugby World Cup, which took place during September and October 2007.

The teams competing were the same as the previous season with one exception; only two Scottish teams participated, as the Scottish Rugby Union scrapped the Border Reivers region at the end of the 2006–07 season.^[3] As in previous seasons, the league was played 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. The losing team may also earn a bonus point if they lose by seven points or less. The losing bonus point system is intended to ensure that both teams compete fully in all matches.^{[citation needed]}

The ten teams competing were the four Irish provinces: Munster, Leinster, Connacht and Ulster; two Scottish regions: Edinburgh Rugby and Glasgow Warriors; and four Welsh regions: Llanelli Scarlets, Cardiff Blues, Ospreys and Newport Gwent Dragons.

Following the end of the 2006–07 Celtic League season, a number of controversial events occurred in Celtic rugby. Mike Phillips moved from the Cardiff Blues to the Ospreys, in a move that would earn him £180,000 a year. The Border Reivers was officially closed as a rugby club, and Edinburgh Rugby were almost expelled from the competition, because of a row with the Scottish Rugby Union.

As a result of increased revenue from governing bodies and TV rights, most clubs were able to expand their squads with the signing of several new players.
