The parish of Sibson-cum-Stibbington sits in the northernmost corner of Cambridgeshire, and forms part of Huntingdon District Council.  The western, northern and eastern boundaries of the Parish are provided by the River Nene as it meanders its way from Peterborough, through the Nene Valley and on past Fotheringhay towards Northampton. The southern boundary of the village is formed by an imaginary line joining the eastern and western sides of the river loop, approx 3 miles from the village centre in the direction of Elton village, and crossing Elton Road to the south of Sibson Airfield.
