Our Lady of Mercy College, Carysfort was a College of Education in Dublin, Ireland from its foundation in 1877 until its closure in 1988. Educating primary school teachers, and located in a parkland campus in Blackrock, it was a recognised college of the National University of Ireland from April 1975. The site is now the premises of the Michael Smurfit Graduate Business School, part of University College Dublin.

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.
