Margot Mayo (May 30, 1910 – May 1974) was an American dance instructor, educator, and collector of folk music.

[4] She was founder of the American Square Dance Group in 1934 and editor of its magazine, Promenade, and published the manual The American Square Dance in 1943.

[1] She and her American Square Dance Group perform on the 1947 Pete Seeger documentary To Hear Your Banjo Play.

[5] The folk revival in New York City was rooted in the resurgent interest in square dancing and folk dancing there in the 1940s, which gave musicians such as Pete Seeger popular exposure.

Among her students was Arlo Guthrie, who learned many of Woody Guthrie's songs at school, and was surprised that other people knew his father's songs better than he did.
