A Disaster Medical Assistance Team (DMAT) is a group of medical and logistical professionals with the ability to quickly move into a disaster area and provide medical care. Under the auspices of the National Disaster Medical System, DMATs can rapidly deploy for any type of disaster that requires a medical response beyond the capabilities of the local system.

The Tennessee team is one of many in the United States affiliated with the National Disaster Medical System, which is a component of the Office of Preparedness and Emergency Operations in the Department of Health and Human Services.
