Abbeyside (Irish: Dún na Mainistreach, meaning "fort of the monastery") is an area in Dungarvan, County Waterford, Ireland. It lies on the east bank of the Colligan River.

MacGrath's Castle was a notable landmark in Abbeyside, overlooking Dungarvan Harbour, until it collapsed in January 1916. It was situated at Friar's Walk in Abbeyside, near the Augustinian abbey. It was a typical tower-house of six floors, two of them supported by stone vaults. The MacGrath family is said to have built it, and it is called MacCragh's Castle in the Civil Survey of 1654. By the mid-18th century the castle was still in a good state of preservation and retained its roof. Following the collapse, fragments of the walls remained up until the early 1960s, but these were removed and now there are no remains visible above ground.
