Mary Street is a predominantly retail street in Dublin, Ireland on the northside of the city contiguous with Henry Street.

St Mary's Church, Dublin is a former Church of Ireland building on the corner of Mary Street and Jervis Street, Dublin, adjacent to Wolfe Tone Square. From the 17th century, the church was a place of worship for parishioners on Dublin's northside, before it was closed in 1986. The church has since been deconsecrated and the building is now a pub and restaurant. The parish also had a chapel of ease - St Mary's - off Dorset Street, more commonly known as "The Black Church".
