Laghy or Laghey (Irish: an Lathaigh) is a small village in County Donegal, Ireland, between Ballintra and Donegal Town. Laghy is one of three villages that makes up the parish of Drumholm, formerly a Civil and Church of Ireland parish, now only used as a division of the Roman Catholic Diocese of Raphoe. The village has a quarry, a supermarket, garden centre, filling station, two public houses, a church with a graveyard, an Orange Order hall, a recycling centre, a Donegal County Council yard and salt depot, and a national school (St Eunan's NS). Laghy is also near two of the most scenic beaches in Ireland, namely Rossnowlagh and Murvagh. Murvagh is also the home to the Donegal Golf Club.
The best known landmarks in this village are The Seven Arches Bridge at the bottom of the main street, and the signpost within the village that says Laghy is 1 km away.
On Mondays to Saturdays Laghy is served by Bus Éireann route 480.  On Sundays the village is served by McGeehan Coaches-Bus Éireann Expressway route 30 providing one journey in each direction to/from Dublin via Enniskillen and Cavan.
St Eunan's National School (Irish: Scoil Náisiúnta Naomh Adhamhnáin) is the only school remaining in the village. It is a Catholic primary school, one of two in the parish of Drumholm, under the patronage of the Bishop of Raphoe, currently Dr Philip Boyce, and is named after Saint Eunan, one of the two patron saints of the diocese. The school was built in the first half of the twentieth century and is in the design of many others built across the country at this time.
The original school had two class rooms, while an extension, which opened in 1992, added a further two to the west end of the existing building, at this point it was and still remains the only school in the village. The school is directly adjacent to the main N15 Sligo to Letterkenny road, which also cuts the school off from the main part of the village. Because of this, when the village was being by-passed for the upgrading of the route, a tunnel had to be constructed to allow those living to the east of the road in the main part of the village to access the school safely.
The current principal is Pauric Daly.
