The Munster Senior League was a Rugby union competition for senior clubs in Munster.
It was first competed for in 1902–03.
[1] Unlike the Munster Senior Cup which is knock-out, the league format means that teams play a number of different games, with the most successful qualifying for the play-offs.
With the establishment of the All-Ireland League in 1991 the competition declined rapidly, and no longer was contested with the same intensity as previously existed.
