St Mary's Church in the Market Place of Wilton, Wiltshire, England, was built in the 15th century.

[2] St Mary's was built on the site of an earlier church at which Bishop Robert de Bingham was consecrated in 1229 before the completion of his cathedral church at Salisbury;[2] his statue is still visible on the west gable.

[3] In 1441 parish records include the purchase of a great bell and c. 1628 a carved pulpit was installed.

In the early 19th century a parish rate was levied for the restoration of the church and a chandelier and pulpit sconces were bought to enable evening services.

[4] In 1845 a new Church of England parish church of St Mary and St Nicholas was built at the instigation of the Countess of Pembroke and her younger son Baron Herbert of Lea, designed by the architect Thomas Henry Wyatt and D. Brandon in the Italianate Romanesque style, with considerable Byzantine influences.
