St Mary Magdalene Church is more than 1,000 years old, with Saxon, Norman, Medieval, Renaissance, Victorian, and 20th and 21st Century elements, the National Churches Trust said.
It was praised for having a large number of volunteers, including the Geddington Volunteer Fire Brigade, to help out with its conservation.
Jim Harker, a volunteer at St Mary Magdalene, said: “This award is a cherished acknowledgement of the wide range of volunteers helping to conserve and care for our church.”
