Mary Pope Osborne is an American author of children's books and audiobook narrator.

Both the series and Osborne have won awards, including for Osborne's charitable efforts at promoting children's literacy. One of four children, Osborne moved around in her childhood before attending the University of North Carolina. Following college, Osborne traveled before moving to New York City.

She went on to write a variety of other children's and young adult books before starting the Magic Tree House series in 1992. Osborne's sister Natalie Pope Boyce has written several compendium books to the Magic Tree House series, sometimes with Osborne's husband Will Osborne.
