The Minerals Management Service (MMS) is a bureau in the U.S. Department of the Interior and is headquartered in Washington DC. MMS is the Federal agency that manages the nation's natural gas, oil and other mineral resources on the outer continental shelf (OCS). The agency also collects, accounts for and disburses more than $8 billion per year in revenues from Federal offshore mineral leases and from onshore mineral leases on Federal and Indian lands.

The MMS’s mission is to manage the ocean energy and mineral resources on the Outer Continental Shelf and Federal and Indian mineral revenues to enhance public and trust benefits, promote responsible use, and realize fair value.
