St Mary's Church is an Anglican parish church in Mold, Flintshire, Wales, and a Grade I listed building. It belongs to the Deanery of Mold, the Archdeaconry of Wrexham and the Diocese of St Asaph of the Church in Wales. It has historical associations with the Stanley family, Earls of Derby and displays heraldic symbols of this, including an Eagle and Child assumed by the family in the 15th century, and the Three Legs of Man, derived from a time when the Stanleys were Lords of Mann. Under Father Rex Matthias, the previous incumbent, the church took on an Anglo-Catholic style of liturgy.
