St Augustine's Church or the Shrine of St Augustine of Canterbury is a Roman Catholic church in Ramsgate, Kent. It was the personal church of Augustus Pugin, the renowned nineteenth-century architect, designer, and reformer. The church is an example of Pugin's design ideas, and forms a central part of Pugin's collection of buildings in Ramsgate. Having built his home, Pugin began work on St Augustine's in 1846 and worked on it until his death in 1852. His sons completed many of the designs. This is the site where Pugin is buried, in a vault beneath the chantry chapel he designed, alongside several members of his family.

Augustine of Canterbury was a Christian monk who became the first archbishop of Canterbury in the year 597. He is considered the "Apostle to the English”.
