Foston is a deserted medieval village and former civil parish, now in the parish of Kilby, in the Blaby district of Leicestershire and lies approximately 6.1 miles (9.8 km) south of the city of Leicester, England.

[6] Mentioned in the Domesday Book Survey of 1086, Foston was a settlement in the Hundred of Guthlaxton, Leicestershire.

[7] The village Church of St Bartholomew is a Grade II* listed building.

[8] The village of Foston is clearly visible on the 1576 map of Warwickshire and Leicestershire, produced (in Latin) by Christopher Saxton as part of his Atlas of England and Wales,[9] but no indication of village settlement size is shown.

A survey by John Nichols, published in 1790, stated only four houses in the village of Foston.
