The Rendlesham Forest incident was a series of reported sightings of unexplained lights near Rendlesham Forest in Suffolk, England in late December 1980 which became linked with claims of UFO landings. The events occurred just outside RAF Woodbridge, which was used at the time by the United States Air Force (USAF). USAF personnel, including deputy base commander Lieutenant Colonel Charles I. Halt, claimed to see things they described as a UFO sighting. The occurrence is the most famous of claimed UFO events to have happened in the United Kingdom, and is among the best-known reported UFO events worldwide. It has been compared to the Roswell UFO incident in the United States and is sometimes referred to as "Britain's Roswell". The UK Ministry of Defence has stated the event posed no threat to national security, and therefore, it was never investigated as a security matter. Sceptics have explained the sightings as a misinterpretation of a series of nocturnal lights: a fireball, the Orfordness Lighthouse and bright stars.

These lights have been attributed by astronomers to a piece of natural debris seen burning up as a fireball (meteor) over southern England at that time. Servicemen initially thought it was a downed aircraft but, upon entering the forest to investigate they saw, according to Halt's memo, what they described as a glowing object, metallic in appearance, with coloured lights. As they attempted to approach the object, it appeared to move through the trees, and "the animals on a nearby farm went into a frenzy". One of the servicemen, Sergeant Jim Penniston, later claimed to have encountered a "craft of unknown origin" while in the forest, although there was no publicised mention of this at the time and there is no corroboration from other witnesses. Shortly after 04:00 local police were called to the scene but reported that the only lights they could see were those from the Orford Ness lighthouse, some miles away on the coast. After daybreak on the morning of 26 December, servicemen returned to a small clearing near the eastern edge of the forest and found three small impressions on the ground in a triangular pattern, as
