Conington (Conington All Saints, or "Conington-juxta-Petriburg") is a village and civil parish in the Huntingdonshire district of Cambridgeshire, England. Conington lies about 6 miles (10 km) south of Peterborough and 2 miles (3 km) north of Sawtry. It is near the A1(M), part of the Great North Road, which follows the course of the Roman Ermine Street. Conington lies within Huntingdonshire, which was once one of the historic counties of England.

Conington was listed in the Domesday Book of 1086, in the Hundred of Normancross in Huntingdonshire; the name of the settlement was written Coninctune in the Domesday Book, when there was just one manor at Conington; the annual rent paid to the lord of the manor in 1066 had been £9 and the rent was the same in 1086.

The Domesday Book also records that there were 27 households at Conington. Estimates for the average size of a household at that time range from 3.5 to 5.0 people. These yield population estimates of 94–135. The survey records there was an area of 15 ploughlands at Conington in 1086. In addition to the arable land, there were some 40 acres (16 hectares) of meadow. The total tax assessment for the manor at Conington was nine geld. By 1086 there was already a church and a priest.

The Cotton Baronetcy of Conington was created in the Baronetage of England on 29 June 1611 for the antiquary Robert Bruce Cotton (1570–1631), who also represented five constituencies in the House of Commons. The novelist, expurgator and editor Henrietta Maria Bowdler was born in Conington in 1750.

In the Second World War, Conington was located next to Royal Air Force Station Glatton. RAF Glatton was constructed to Class "A" standards to support heavy bombers in 1943, as it was to be used by the US Army Air Forces. The 457th Bombardment Group (Heavy) arrived on 21 January 1944. The recognisable tail code of the 457th was the "triangle U" painted on the vertical stabilizers of the Boeing B-17 Flying Fortresses which operated from the air base. The 457th Bomb Group operated from RAF Glatton from January 1944 until 20 April 1945, when it completed its 237th and last combat mission at the conclusion of the war. In All Saints' Church, Conington is a memorial to the 457th Bomb Group.
