Keadeen Mountain at 653 m, is the 152nd–highest peak in Ireland on the Arderin scale, and the 184th–highest peak on the Vandeleur-Lynam scale. Keadeen is situated at the far southwestern end of the Wicklow Mountains range, separated from the large massif of Lugnaquilla on its own small isolated massif with Carrig Mountain 571 m; it overlooks the Glen of Imaal from the south.

Naming

According to Irish academic Paul Tempan, "Keadeen" is also the name of a townland in the nearby parish of Kilranelagh. In Irish the peak was sometimes called Céidín Uí Mháil in full, which was a name derived from the native group who gave their name to the nearby Glen of Imaal.

History

Dwyer–McAllister Cottage is at the northern base of Keadeen at Derrynamuck, where Michael Dwyer, the 1798 rebellion United Irishmen leader, escaped from the British soldier's siege on Sam McAllister cottage in December 1799 up the slopes of the mountain.
