The United States Fleet Marine Forces (FMF) are combined general and special purpose forces within the United States Department of the Navy that perform offensive amphibious or expeditionary warfare and defensive maritime employment. The Fleet Marine Forces provide the National Command Authority (NCA) with a responsive force that can conduct operations in any spectrum of conflict around the globe.

The Fleet Marine Forces (FMF) consists of Marine Corps' operating forces components that constitute the Fleet Marine Forces on the Pacific and Atlantic coasts, or within its "designate(s)". While the FMF is a Marine Corps organization, the FMF is a type command under the operational control of Navy fleet commanders; the Commandant of the Marine Corps (CMC) retains administrative and training control.

The Commanding General of the Fleet Marine Force; either its Pacific (CG FMFPAC) or Atlantic (CG FMFLANT) command, are responsible for the administration and training of all of the subordinate units of the Marine Corps Forces (MARCORFOR). The subordinate units of the Fleet Marine Forces come under the operational control of the commanders, U.S. Fleet Force Command (formerly Atlantic Fleet) or United States Pacific Fleet, when deployed.

The commanders of Marine Forces Command (MARFORCOM) and Pacific (MARFORPAC) serve as Marine Corps component commanders to their respective combatant commanders and may also serve as commanding generals of Fleet Marine Forces (FMFs) Atlantic, or Pacific.

The operating forces of the Marine Corps are currently organized into two Fleet Marine Forces (FMF):
