Sundon is a parish in Bedfordshire consisting of two villages:
- Upper Sundon at the top of the hill, the larger village; and
- Lower Sundon, a hamlet, but the location of the parish church.
Sundon is perilously close to the edge of Luton just to the south and indeed within the town area is Sundon Park, which was formerly part of the parish, until swallowed by the town.
The parish church is St Mary in Lower Sundon, a thirteenth century church with two rare survivals: an ancient screen and wall paintings. There are old pews in the church too and a parish chest sits in the church.
