St Mary's Church, Castle Street

St Mary's Church, Castle Street is an independent church within the Continuing Anglican movement. It is located in the town centre of Reading, in the English county of Berkshire, and is a few yards from the similarly named, but much older Minster Church of St Mary the Virgin.

In 1798, there was a disagreement between the Bishop and the congregation of St Giles' Church in nearby Southampton Street. Many of the congregation left and founded a new chapel in Castle Street, on the site of Reading's old gaol. This chapel eventually became the Church of St Mary, Castle Street.
