2nd Medical Group (2 Med Gp) is a formation of the British Army under Field Army Troops. It predominantly provides deployed hospital care via 11 Multi-Role Medical Regiments. It also provides specialist medical capabilities via three Nationally Recruited Reserve Units; 306 Hospital Support Regiment, 335 Medical Evacuation Regiment and the Medical Operational Support Unit.

Headquarters 2nd Medical Group, formerly known as 2nd Medical Brigade, was initially formed at Imphal Barracks, York under the title of The Medical Group on 1 April 2002, as a result of the Strategic Defence Review.

In March 2020, as part of Operation Rescript, 256th (London and South East) Multi-Role Medical Regiment, then known as 256 Field Hospital, helped construct a temporary critical care hospital, named NHS Nightingale Hospital London, during the COVID-19 pandemic in the United Kingdom.

Under the Future Soldier programme announced on 25 November 2021, the formation was reduced to a Colonel's Command. Subsequently, many units were moved under direct command of the divisions. The formerly named 2 Medical Brigade became 2 Medical Group. In addition, the group transferred from 1st Division to Field Army Troops, reporting directly to Commander Field Army. The role of the group was described as follows: "The 2nd Medical Group will generate field hospitals and task-organised medical support to the deployed force. It will be significantly reinforced by Army Reserve multi-role medical regiments and specialist medical capabilities.

The HQ has operational command of 2 Regular Multi-Role Medical Regiments, 9 Reserve Multi-Role Medical Regiments, a Reserve medical evacuation regiment, a Reserve hospital support regiment, and the Reserve Medical Operations Support Unit, which provides small teams of pre-qualified medical staff officers to support operations and exercises. The group also provides the enhanced medical operational command and control (C2) capability lost by the Army Medical Services (AMS). The group has significantly raised the quality of pre-deployment medical training, seeing it previously provide a high standard of field medical care at field hospitals in Afghanistan.

The soldiers and officers of 306 Hospital Support Regiment are all fulltime NHS Consultants and Specialist Nurses, in niche areas such as women's health, paediatrics, head & neck, CT scanning, and neurosurgical, who serve as reservists in their spare time.

335 Medical Evacuation Regiment are specialists in medevac or 'in transit care', moving critical care patients across land operations, providing capabilities such as Medical Emergency Response Teams (MERT), Forward Medical Evacuation Teams, Pre-Hospital Treatment Teams, Tactical Medical Evacuation Teams. It also provides ambulance crews that are trained in all NATO ambulance platforms. The regiment has deployed personnel on every major offensive, peacekeeping and humanitarian operation since its formation in 2005, including Operation GRITROCK (Sierra Leone), Operation HERRICK (Afghanistan), Operation TELIC (Iraq), Operation TOSCA (Cyprus) and Operation TRENTON (South Sudan).

The Group Headquarters is based at Queen Elizabeth Barracks, Strensall, North Yorkshire. The barracks had been planned to close in 2024, however Defence Procurement Minister, James Cartlidge, later announced that the barracks would be retained and receive additional investment to remain home of the 2nd Medical Group for the future.
