The Many Faces of Ernie Disguise Kit is a 1980 Sesame Street activity set that allows readers to follow along with the story of the 1979 Little Golden Book The Many Faces of Ernie. In the storybook, Ernie gets a disguise kit in the mail, and tries to dress up and fool Bert.

The Disguise Kit includes the storybook, an Ernie mask, a Bert mask, and four accessories that "Ernie" can use to create disguises.
