Coloma (formerly, Colluma and Culloma) is a census-designated place in El Dorado County, California, USA. It is approximately 36 miles (58 km) northeast of Sacramento, California. Coloma is most noted for being the site where James W. Marshall found gold in the Sierra Nevada, at Sutter's Mill on January 24, 1848, leading to the California Gold Rush. Coloma's population is 529.
Coloma grew around Sutter's Mill following the finding of gold. A post office was established in 1849 under the name Culloma, changing to Coloma in 1851.
One of Coloma's earliest settlers was Silas Sanderson (1824–1886), who went on to become the 7th Chief Justice of California.
