The townland name is an anglicisation of the Gaelic placename Sliabh Bricín which means ‘The Hill of Saint Bricín'. It derives its name from St. Bricín who was the abbot of Tomregan University in 637 AD which was in the nearby townland of Mullynagolman. The oldest surviving mention of the name is in a patent of King James I dated 7 July 1613, where it is spelled Slewbricken.
