Cliffdell is an unincorporated community in Yakima County, Washington, United States, located approximately 23 miles west of Ellensburg. As of the 2020 census, Cliffdell had a population of 114. The community, located on SR 410 and the Naches River, was originally named Spring Flats. In 1920, it was renamed Cliffdell in honor of Cliff and Della Schott of Seattle. The Schotts were friends of homesteader Russell Davison, who developed much of the area for summer homes. Cliffdell was the site of a temporary army camp once used by Captain William O. Slaughter in 1855.
Between the 2010 and 2020 censuses its population grew from 104 to 114 (+10%).
