Sierra Army Depot (SIAD) is a United States Army post and military equipment storage facility located near the unincorporated community of Herlong, California. It was built in 1942 as one of several ammunition storage facilities located far enough inland to be safe from Japanese attack, yet close enough to western military posts and ports to facilitate shipment of supplies. The site also met the requirement that the depot be in a dry and isolated area.

The depot is a subordinate of US Army Tank-Automotive and Armaments Command (TACOM).
