"Are There Men on the Moon?" is an 11-page essay by Winston Churchill on the possibility of extraterrestrial life. The essay was published in the Sunday Dispatch on 8 March 1942 and republished as part of The Collected Essays of Sir Winston Churchill in 1975.
Two unpublished versions of the essay are also known: A 1950s version held by the National Churchill Museum in Fulton, Missouri, named "Are We Alone in the Universe?" and an earlier 1939 draft titled "Are We Alone in Space?", which is part of the collection of the Churchill Archives Centre at the University of Cambridge. The 1950s version of the essay gained media attention after an analysis of it by Mario Livio was published in Nature in 2017.
