Frieston is a village in the South Kesteven district of Lincolnshire, England.

It is situated just west of the A607 road, and 7 miles (11 km) north from the market town of Grantham.

Kesteven was one of the three divisions (formally known as parts) of the traditional county of Lincolnshire.

[citation needed] It is believed that the name 'Frieston' is derived from the Frisians, who are known to have settled in Britain during the 5th and 6th Centuries AD.

The thorpe element of Caythorpe indicates a secondary settlement by Vikings, in this case probably Danes, at some time between 800 and 1050.
