Dunmore East (Irish: Dún Mór Thóir, meaning 'east big fort')[2] is a popular tourist and fishing village in County Waterford, Ireland.

Situated on the west side of Waterford Harbour on Ireland's southeastern coast, it lies within the barony of Gaultier (An Gháilltír – "land of the foreigner" in Irish[3]); a reference to the influx of Viking and Norman settlers in the area.

[5] In 1640, Lord Power of Curraghmore, who owned a large amount of property in the area, built a castle on the cliff overlooking the strand about two hundred metres from St. Andrew's Church.

[6] The fishermen's homes were situated in the Lower Village near the Strand Inn and boats were launched from the slip at Lawlor's Beach before the harbour was built.

[7] In 1812, a decision was made at Westminster to create an entirely new landing point for passengers and the Royal Mail coming to Ireland from London and southern England.

[8] In 1814, dramatic changes took place when Alexander Nimmo, the Scottish engineer (builder of Limerick's Sarsfield Bridge) commenced work on the new harbour at Dunmore.

[9] By then (1837) the harbour had started to silt up, and the arrival of steam meant that the winding river could be negotiated easily, so the packet station was transferred to Waterford.

[12] It also then developed into a very popular tourist resort and it is now a favourite port of call for large cruise liners visiting the south-east of Ireland.

Gaultier GAA which focuses primarily on Gaelic Football is located just outside the village, across the road from Dunmore FC soccer club.

They operate several enterprises, including a bakery, a bookshop, a petrol station, and training schools for woodworking, forestry, and animal husbandry.

Tourism in Dunmore East is supported by boating and sailing facilities, holiday homes, traditional pubs, a golf course and several hotels.
