Maumtrasna, historically Formnamore (Irish: Formna Mór, 'the great shoulder'),[2] is the highest of the Partry Mountains in south County Mayo, Ireland, rising to 682m (2,238feet) above sea level.[1] The summit is broad and flat with several ridges running off it, including Skeltia (An Scoltach), Benwee (Binn Bhuí), Buckaun (An Bocán)[2] and Binnaw (Binn Fheá).[3] The peak of Knocklaur (Cnoc Láir, 'middle hill') stands on the ridge between Maumtrasna and Devilsmother mountains.[4]
The name 'Maumtrasna' comes from Mám Trasna, meaning "the pass across", and originally meant the hill pass on the road between Lough Nafooey and Lough Mask.[2] The townland of Maumtrasna is on the south bank of the Srahnalong river. The townland was the location of the infamous Maumtrasna murders in 1882.
