St Mary's Church is in the town centre of Warrington, Cheshire, England. It is recorded in the National Heritage List for England as a designated Grade II listed building, and is an active Roman Catholic church. The parish was established and served by Benedictine monks from Ampleforth Abbey, but following the withdrawal of Ampleforth Abbey from the parish in 2012, it is now served by the priest from St Benedict's Church, Warrington. It is well known for the beauty and reverence of its liturgy and the ambition and excellence of the church choir and music.
