Northchurch is a village and civil parish in the Bulbourne valley in the county of Hertfordshire in the United Kingdom.

Part of the original Saxon building remains in the south and west walls.

Flint wall extensions were built between the 11th and 14th centuries, to form a cruciform building.

Northchurch today, however, is recognised as a separate village with its own Parish Council.

St Mary's churchyard contains the grave of Peter the Wild Boy, a German feral child adopted at the court of King George I and II.
