Leenaun Hill (Irish: An Meall Dubh, meaning 'black knoll') at 618 metres (2,028 ft), is the 201st–highest peak in Ireland on the Arderin scale, and the 243rd–highest peak on the Vandeleur-Lynam scale. Leenaun Hill lies on a massif that overlooks Leenaun village and Killary Harbour, and which is at the far northeastern sector of the Maumturks mountain range in the Connemara National Park in Galway, Ireland; this massif is connected to the main range via the "Col of Despondency". Leenaun Hill is the 6th-highest mountain in the Maumturks, and its grassy massif, constructed from sandstone and siltstone, contrasts with the rocky ridges and summits constructed from quartzites, grits, and graphitic, of the middle and southern sectors of the range.
