The 2nd Regiment California Volunteer Cavalry was a cavalry regiment in the Union Army during the American Civil War. It spent its entire term of service in the western United States, with most of its companies dispersed to various posts.

2nd Regiment California Volunteer Cavalry was organized under the President's second call upon the State for troops in August 1861. By October 30, 1861, the regiment was organized and mustered into the service. The companies were assembled at Camp Alert in San Francisco. After completing the organization of the regiment, and a short period for drill and discipline, the regiment was sent, by companies, to various posts within the Department of the Pacific. The final muster out of the regiment was in March, 1866.
