The Leinster Senior Cup is a major rugby competition in Ireland, involving all senior rugby clubs in Leinster, i.e., clubs from Leinster competing in the All-Ireland League. From 2006 until 2016 it was known as the Leinster Senior League Cup during the period when the Leinster Senior League had been discontinued, but reverted to its traditional name for the 2016–17 season upon the revival of the Senior League. From 2011 to 2016 only the top senior teams competed and those in the lower divisions of the All-Ireland League competed for the Leinster Senior League Shield.
