Little Gransden Airfield (ICAO: EGMJ) is an unlicensed airfield located near the village of Little Gransden, 5 NM (9.3 km; 5.8 mi) southeast of St Neots, Cambridgeshire, England.

It is also the home of Yak UK Ltd., who import, service and sell the Yakovlev range of piston engined aerobatic aircraft.

Each summer the airfield is home to Little Gransden Families Day Out Air & Vintage Vehicle Show which raises money for the Children in Need charity.

In 1992 South Cambridgeshire District Council served a planning contravention notice on the airfield, which had been operating since 1966.

The airfield, supported by planning consultant Peter Kember and some of some local villagers, argued at a public enquiry that they were operating lawfully based on 10 years' continuous use.
