Rush, County Dublin

Rush (Irish: Ros Eó, meaning 'peninsula of the yew trees' [ˈɾˠɔsˠ oː]), officially An Ros, is a small seaside commuter town in Fingal, County Dublin, Ireland. Rush lies on the Irish Sea coast, between Skerries and Lusk, and has a small harbour. It had a population at the 2022 census of 10,875.

Rush was once known as the "market garden of Ireland" for the large role market gardening played in its economy and culture. In the 21st century, Rush is no longer a major centre of national horticulture and has instead evolved into a growing commuter town on the northern fringes of the Greater Dublin Area.

Rush lies on the Irish Sea coast, on the angle where the R128 regional road turns from running east–west from Lusk to go north–south to Skerries. It has a small harbour.

Rush is in a slightly hilly coastal area. Four streams come to the sea in the vicinity, St. Catherine's Stream, Kenure Stream, the Rush Town Stream, and a combined flow at the western edge of the town; some occasionally cause flooding. The middle two cross Rush's North Strand beach.

Rush is also a townland in the civil parish of Lusk in the barony of Balrothery East.

There is evidence of settlement in the Rush area dating back to Neolithic times. Flint tools have been found in the area and there is a passage grave and cist located off the Skerries Road on the headland to the north of North Beach.

In medieval times Rush was a manor of the Earl of Ormond.

In 1744 a description of Rush by a traveller runs as follows:
