Lower Rancheria is a former gold-mining camp in Amador County, California.

It was located on Rancheria Creek 2 miles (3.2 km) east-southeast of Drytown,[2] at an elevation of 1017 feet (310 m).

Placer mining began at Lower Rancheria in 1848.

[2] Prior to 1855, the camp at Lower Rancheria was mostly populated by Spanish-speaking miners.

On 6 August 1855 a series of murders were carried out at the camp by a group of Mexicans, who killed five men and one women and who also robbed the contents of a safe.
