Marilyn Waltz (born October 10, c. 1930 in Waukesha, Wisconsin) is an American actress and model.

She was Playboy magazine's first three-time Playmate of the Month, appearing in the February 1954, April 1954 and April 1955 issues. For Waltz' first Playmate appearance, however, she was billed as “Margaret Scott”. For many years it was assumed that the two people were just that—two separate people—until the mid 1990s, when Hugh Hefner, while looking through photos in preparation for The Playmate Book, noticed stark similarities between the models. After he speculated in the book about this, Waltz notified Playboy that she in fact was Margaret Scott.

Though the title of Playmate of the Year was not officially created until 1960, Waltz received more fan mail than any other Playmate in 1954—ironically, for her "Margaret Scott" appearance—and thus could be considered PMOY, unofficially.

Waltz also was a singer and commercial actress, and did layouts for other men's magazines prior to her Playboy work.
