Legananny Dolmen is a megalithic dolmen or cromlech nine miles southeast of Banbridge and three miles north of Castlewellan, both in County Down, Northern Ireland. It is on the slopes of Slieve Croob near the village of Leitrim, in Drumgooland parish, nestled between the farmer's stone wall and a back road. It is a State Care Historic Monument sited in the townland of Legananny, in Banbridge District Council area, at grid ref: J2887 4339.
This tripod dolmen has a capstone over 3m long and 1.8m from the ground. It dates to the Neolithic period, making the monument approximately 5,000 years old. Such portal tombs were funerary sites for the disposal of the dead in Neolithic society. The heavy stones would have been dragged some distance before being set in place. The three supporting stones are unusually long and there are slight traces of a cairn which must have been far more extensive. Some urns were found underneath.
The name Legananny is believed to be derived from the Irish: Liagán Áine meaning "Áine's standing stone" – Áine being an Irish goddess.
