The U.S. Marine Corps Forces Cyberspace Command (abbreviated as MARFORCYBER) is a functional formation of the United States Marine Corps to protect critical infrastructure from cyberattack. Marine Corps Forces Cyberspace Command is the Marine Corps component to U.S. Cyber Command. It comprises a command element, the Marine Corps Cyber Operations Group, and a company from the Marine Corps Cryptologic Support Battalion (MCSB), a total of approximately 800 personnel. MARFORCYBER was established on January 21, 2010 under the command of LtGen George J. Flynn, and as of September 8, 2015, it is commanded by MGen Loretta E. Reynolds.

The Secretary of Defense recognized the significance of the cyberspace domain to national security, and directed the establishment of CYBERCOM as a sub-unified command under STRATCOM. CYBERCOM's primary objective is to integrate the cyberspace operations capabilities of the services and agencies in support of the National Strategy to Secure Cyberspace (NSSC).

In response, the Marine Corps established MARFORCYBER in October 2009 (this was complemented by the standing up of the Fleet Cyber Command, U.S. Army Cyberspace Command (ARCYBER), and Air Force Cyberspace Command (AFCYBER). MARFORCYBER's mission, in addition to its standard service component responsibilities, is to: plan, coordinate, integrate, synchronize, and direct the Corps' full spectrum of cyberspace operations. This includes Department of Defense (DoD) Information Network (DoDIN) operations, Defensive Cyber Operations (DCO), and planning and, when required, executing Offensive Cyberspace Operations (OCO). These operations support MAGTF, Joint and combined cyberspace requirements that enable freedom of action across all warfighting domains and deny the same to adversarial forces.
