Twain Harte is a census-designated place (CDP) in Tuolumne County, California, United States. The population was 2,226 at the 2010 census, down from 2,586 at the 2000 census. Its name is derived from the last names of two famous authors who lived in California, Mark Twain and Bret Harte.
Twain Harte is both a summer and winter vacation community situated at the transition zone between the oak Forest of the California foothills and the mixed pine and fir forest of the Sierra Nevada Mountains. Summers are warm during the Day and the nights are generally mild; making Twain Harte a pleasant escape from the long, hot summers of the California Central Valley.
