The United States Army Soldier Systems Center (SSC) is a military research complex and installation in Natick, Massachusetts charged by the U.S. Department of Defense with the research and development (including fielding and sustainment) of food, clothing, shelters, airdrop systems, and other servicemember support items for the U.S. military. The installation includes facilities from all the military services, not just the Army, and is so configured to allow cross-service cooperation and collaboration both within the facility and with the many academic, industrial and governmental institutions in the Greater Boston Area.

The SSC is sometimes called the Natick Army Labs, although this designation more properly refers to one of its tenant units, the United States Army Natick Soldier Research, Development and Engineering Center (NSRDEC).
