Thankerton is a small village in South Lanarkshire, Scotland, United Kingdom. It is located between Biggar and Lanark. It is situated between Quothquan Law and Tinto (two local hills).
To the west of Thankerton is a hamlet called Eastend, on the south edge of the Carmichael Estate, whose main house, Eastend House, was used by the Polish Army between August 1940 and May 1941. A stone in the house, with the Polish eagle on it, commemorates the event.
