Tallington is a village and civil parish in the South Kesteven district of Lincolnshire, England.

From the East Coast Main Line south-east of the village, the parish boundary follows the River Welland to the west, it meets Uffington and crosses the A1175 a half-mile west of the village at the point where the pylons cross the road, then skirts the edge of Casewick Park.

It skirts the northern edge of Barholm Lodge, across the north section of Tallington Lakes and meets West Deeping at King Street.

Remains of bridge piers were uncovered during archaeological excavations carried out in 1998 when a water pipeline running from Tallington to West Deeping was installed.

At the Tallington Lakes Leisure Park, made from gravel pits, is a dry ski slope and water activities with a campsite.

Tallington Lakes are situated directly east of the former Dow-Mac concrete works, and are formed from its gravel pits.
