Deeping Gate is a village and civil parish, lying on the River Welland in Cambridgeshire. Traditionally, the area was part of the Soke of Peterborough, geographically considered a part of Northamptonshire; it now falls within the City of Peterborough unitary authority area of Cambridgeshire. With a very small population, void of any major services, including a post office or even a chapel, the community depends on nearby Market Deeping, one and a quarter miles (2.0 km) north of the river in Lincolnshire, for economic and market services. The parish had a population of 258 males and 257 females according to the 2011 Census. Renaissance composer Robert Fayrfax (Fairfax) was a native of the village. Fairfax House, the most prominent and grand property in the village, was home to the Fairfax Family.
