The Pentagon Force Protection Agency (PFPA) is a federal law enforcement agency within the United States Department of Defense charged with protecting and safeguarding the occupants, visitors, and infrastructure of The Pentagon, the Mark Center Building, the Defense Health Agency headquarters, the United States Court of Appeals for the Armed Forces and other assigned DoD-occupied leased facilities within the National Capitol Region.

In late 2022, Chris Bargery became acting Director after Daniel P. Walsh left the Pentagon Force Protection Agency.

Within this scope, he exercises the authorities of the Secretary of Defense under 10 U.S.C 2674 with respect to force protection, security, and law enforcement.

PPD's role is to provide law enforcement and protective security services for The Pentagon and other Office of the Secretary of Defense (OSD) activities in the National Capital Region.

These services include patrol, response, and investigation of criminal activity as well as protection of designated Defense officials.
