St Mary's Church is in Fernyhalgh Lane, Broughton, Lancashire, England. It is a Roman Catholic church located near the shrine at Ladyewell House. The church was built in 1792–94 to provide services for pilgrims when the chapel at the house became too small for the numbers attending. Attached to the east of the church is the presbytery, and both are built in red brick with sandstone dressings with slate roofs. Near the church is a school built in 1836, and later used for other purposes. Ladyewell House contains a 16th-century altar, relics and memorabilia, and in garden are a chapel and a holy well. The church and house are in active use for church services, pilgrimages, and visitors.
