Edith Kellogg Dunton (December 28, 1875 – December 31, 1944) was the author of a popular series of early 20th century juvenile novels called the "Betty Wales" series, which she wrote under the pseudonym Margaret Warde.

Dunton was born in Rutland, Vermont, the daughter of Walter C. Dunton and Miriam E. Barrett.

Dunton's identity as the author of the series was not leaked until late 1907, at which time she was also writing under her own name as a critic for The Dial magazine in Chicago.

[6][7] The popularity of the Betty Wales series, which followed the story of the title character from her freshman year at the fictional Harding College through beyond graduation, led to the introduction of a line of "Betty Wales Dresses" in 1915, where each purchase entitled the buyer to a free book from the series.

[9][10] Dunton died in late 1944 and was buried at the Evergreen Cemetery in Rutland.
