Wide Field Camera observations of the outer field of M101, obtained in Cycle 3, have been analyzed as part of the ongoing Hubble Space Telescope Key Project on the Extragalactic Distance Scale. We report the discovery of approximately 30 Cepheids spanning a range of periods from about 10 to 50 days. The resulting light curves and Period-Luminosity relationship are presented and the implications for the distance to M101 are discussed.
