The community's beginnings date back to the California Gold Rush and it prospered during the era of hydraulic mining at nearby Malakoff Diggins State Historic Park from 1850 to 1884. Beginning in 1867, it was included on the route for the first long-distance telephone line, a historical landmark, between French Corral and French Lake.
The original name San Juan was bestowed by a veteran of the Mexican–American War who settled there in 1853 because he thought the site looked like San Juan de Ulúa near Veracruz.
