St. Mary's Abbey was a former Cistercian abbey located near the junction of Abbey Street and Capel Street in Dublin, Ireland. Its territory stretched from the district known as Oxmanstown down along the River Liffey until it met the sea. It also owned large estates in other parts of Ireland. It was one of several liberties that existed in Dublin since the arrival of the Anglo-Normans in the 12th century, which gave it jurisdiction over its lands.

Abbey Street is a major street, located on the Northside of Dublin city centre, running from the Customs House and Beresford Place in the east to Capel Street in the west, where it continues as Mary's Abbey. The street is served by two Luas light rail stops, one at Jervis Street and Abbey Street Luas stop near O'Connell Street. About 1 km in length, it is divided into Abbey Street Upper, Abbey Street Middle and Abbey Street Lower. Abbey Street Old is a laneway to the rear of the buildings on the south side of Abbey Street Lower.
