Hartford is a suburb of Huntingdon and former civil parish, now in the parish of Huntingdon, in Cambridgeshire, England. Historically part of Huntingdonshire, it is not far west of Wyton. It lies on the A141 road and on the north bank of the River Great Ouse, upon which it has a significant marina. The village is not to be confused with the much larger town of Hertford, some 38 miles to the south-east. In 1931 the parish had a population of 464.
