St Michael's Church is an Anglican place of worship situated on Bailiffgate in the town of Alnwick in Northumberland, England. The current building dates from the 15th century but a 12th-century Norman chapel stood on the site prior to this; reports of an earlier 8th-century Saxon chapel are unconfirmed. The church is dedicated to St Michael the Archangel, in earlier times it was also dedicated to St Mary as well. It is a Grade I listed building.
