St. John the Baptist, Blackrock is a Roman Catholic church in the parish of Blackrock, Ireland. The church is still in use and named after the Saint John the Baptist. It is located on Temple Road, Blackrock, County Dublin.

The church was designed by the architect Patrick Byrne, who was educated at the Dublin Society Schools. It is one of the finest examples of the Gothic revival style in Ireland and was the first to be built in the Dublin Archdiocese. It is said to be inspired by the ideas of Augustus Welby Pugin (1812-1852).

The initial building consisted of the nave, chancel and bell tower. To the rear of the church, two carved heads can be seen up high on either side of the rose window. The head on the left depicts St. John the Baptist, while the head on the right depicts the Archbishop Daniel Murray.
