Family Readiness Group (FRG) is a command-sponsored organization of family members, volunteers, soldiers, and civilian employees associated with a particular unit within the United States Army, the United States Army Reserve, and the Army National Guard communities. They are normally organized at company and battalion levels, and fall under the responsibility of the unit's commanding officer.

FRG's are established to provide activities and support to enhance the flow of information, increase the resiliency of unit soldiers and their families, provide practical tools for adjusting to military deployments and separations, and enhance the well-being and esprit de corps within the unit. Since one of the goals of an FRG is to support the military mission through provision of support, outreach, and information to family members, certain FRG activities are essential and common to all groups, and include member meetings, staff and committee meetings, publication and distribution of newsletters, maintenance of virtual FRG websites, maintenance of updated rosters and readiness information, and member telephone trees and e-mail distribution lists.

All army units, both active and reserve, sponsor FRGs as an avenue of mutual support and assistance, and as a network of communications among the family members, the chain of command, chain of concern, and community resources. The FRG also provides feedback to the command on the state of the unit "family" and is considered a unit commander’s program.

FRGs developed out of military family support groups as well as less formal officer and enlisted wives clubs, telephone and social rosters, volunteer groups, and clubs. Modern FRGs are a fully defined and officially supported function within the U.S. Army, and include men, women, and children from throughout the military community.
