Threekingham listenⓘ (sometimes Threckingham or Tricengham) is a village in the North Kesteven district of Lincolnshire, England.

[1] It is situated on the A52 Grantham to Boston road, 6 miles (10 km) south from Sleaford, and close to the A15 Threekingham Bar roundabout.

Mareham Lane, the Roman Road aligned with King Street, crosses the A15 at Threekingham.

[7] Historian David Roffe describes St Ætheldreda's connection with Stow Green, saying the site, called "Ædeldreðestowe," was chosen because the saint's staff took root and sprouted leaves there.

[10] There are ancient earthworks and a mound called Threekingham Beacon to the west of the village.
