Connacht Senior League (rugby union)

The Connacht Senior League is a rugby union competition for senior clubs in the Irish province of Connacht. It was first played for in 1925-26.

It has traditionally been ranked second in importance to the Connacht Senior Cup. With the formation of the All-Ireland League it has declined in importance somewhat with the advent of Professional Rugby, and the participation of the regional team Connacht Rugby in competitions such as the United Rugby Championship and European Rugby Champions Cup.
