Dexthorpe is a deserted medieval village in the East Lindsey district of Lincolnshire, England.

It is in the parish of Dalby, and 3.5 miles (5.6 km) north from Spilsby, 1 mile (1.6 km) south-west from Ulceby, and 400 yards (366 m) east from the A16 road.

Dexthorpe is listed in the 1086 Domesday Book as part of the Candleshoe Hundred in the South Riding of Lindsey.

It held 23 households, 8 villagers, 11 smallholders and 47 freemen, with 16 ploughlands, 2 churches and 80 acres (0.3 km2) of meadow.

[2][3] In 1829, Edmund Oldfield wrote in his book A topographical and historical account of Wainfleet in the Wapentake of Candleshoe in the County of Lincoln, that "the inhabitants of Dexthorpe pay church rates to the incumbent of Well", and that the number of inhabitants in Dalby and Dexthorpe in 1801 were 50, in 1811 there were 71 and by 1821 had risen again to 99.
