The Kelly–Hopkinsville encounter (also known as the Hopkinsville Goblins Case or Kelly Green Men Case) was a claimed close encounter with extraterrestrial beings in 1955 near the communities of Kelly and Hopkinsville in Christian County, Kentucky, United States. UFOlogists regard it as one of the most significant and well-documented cases in the history of UFO incidents, while skeptics say the reports were due to "the effects of excitement" and misidentification of natural phenomena such as meteors and owls. The United States Air Force classified the alleged incident as a hoax in the Project Blue Book files.

Sutton, their respective wives Vera and Alene, Alene's brother O.P. Baker, and Billy Ray Taylor and his wife June. Both the Taylors, "Lucky", and Vera Sutton were reportedly itinerant carnival workers who were visiting the farmhouse. The next day, neighbors told two officers that the families had "packed up and left" after claiming "the creatures had returned about 3:30 in the morning". Press coverage The family's claims received widespread coverage in local and national press. Early articles did not refer to "little green men"; the color was later added to some newspaper stories. Estimates of the size of the alleged creatures varied from , and details such as "large pointed ears, clawlike hands, eyes that glowed yellow and spindly
