Mark Kendall Sargent (born c. 1969) is an American conspiracy theorist, who is one of the leading proponents of, and recruiters for, the discredited flat Earth conspiracy theory in the United States. According to critics, his YouTube videos have greatly accelerated the popularization of modern flat Earth belief, one without scientific merit.
