RAF Stenigot is a former Second World War radar station situated at Stenigot, near Donington on Bain, Lincolnshire.

It was built in 1938 by Blaw-Knox as part of the Chain Home early-warning radar network. Initially, the site's main feature was an octet of aerial towers. These were supported by some low-lying buildings.

The station was upgraded in 1959 to GEE H communications relay site as part of the ACE High programme, which involved adding four tropospheric scatter dishes. The site was decommissioned in the late 1980s and was mostly demolished by 1996.

The radar tower is a Grade II listed structure because it is the best preserved and most complete Chain Home transmitter tower surviving in its original location in the British Isles. The site is still in use by the RAF Aerial Erector School for selection tests for possible recruits.

Stenigot Tower is also used by various two way radio providers as a common base repeater site due to its vast coverage of Lincolnshire.

Three of four dishes on site were scrapped in the winter of 2018. A local construction firm admitted to scrapping three of the four dishes, the legality of this is disputed. The first dish was removed from its supports sometime before 14 October, with two more dishes being felled over the following days. The fourth and last remaining dish was removed in mid to end–November 2020.
