Sandtoft is a hamlet in the civil parish of Belton, North Lincolnshire, England.

Sandtoft is in Hatfield Chase on the Isle of Axholme, 3 miles (5 km) north-west from Epworth. The village was served by the Isle of Axholme Joint Railway and was on the Fockerby branch with a goods station serving the former RAF airfield.

RAF Sandtoft was an RAF Bomber Command airfield. It opened in April 1944, closed in November 1945 and was sold for civilian uses in 1955. Today part of the site is Sandtoft Airfield and The Trolleybus Museum at Sandtoft, Europe's largest trolleybus museum, is on another part.

Sandtoft and nearby Epworth, Lincolnshire were centres of unrest during the 17th draining of The Fens.
