St John the Baptist Parish Church is an Anglican place of worship situated in the village of Alnmouth in Northumberland, England.

The church was built by the first Norman Earl of Northumbria around the time of Alnmouth's foundation in the 12th century and named in honour of Saint Waleric.

This church declined rapidly in the 16th century as a result of the Dissolution of the Monasteries, additionally it was gradually destroyed as the River Aln changed course over a period of time and was finally brought down in the great storm of Christmas 1806.

From 1859 a temporary chapel was created for worship in the town at Hindmarsh Hall, an old granary, and this was used until a new church could be built.

The sanctuary ceiling is significant because of its shape and decoration, it has the church organ on its left hand side.
