The Irish name Gabhal Mhór seems to have developed from Sliabh na Gaibhle meaning "mountain of the fork". The anglicised form Slieve Goul is found in several 19th century sources. Gabhal Mhór ("big fork") stands in contrast to its lower neighbouring peak Gabhal Bheag ("little fork"), anglicised as Gowlbeg.
