Blackrock railway station serves Blackrock in Dún Laoghaire–Rathdown, Ireland. It opened publicly on 17 December 1834 and is one of the three original stations on the Dublin and Kingstown Railway (D&KR), the oldest public passenger railway in Ireland.

Blackrock is an affluent suburb of Dublin, Ireland, 3 km (1.9 mi) northwest of Dún Laoghaire. It is named after the local geological rock formation to be found in the area of Blackrock Park. In the late 18th century, the Blackrock Road was a common place for highway robberies. The Blackrock baths, provided for by the railway company in 1839, became popular in the 19th century but Blackrock is now a tourist destination.
