The British Armed Forces are the military forces responsible for the defence of the United Kingdom, its Overseas Territories and the Crown Dependencies. They also promote the UK's wider interests, support international peacekeeping efforts and provide humanitarian aid.

Since the formation of the Kingdom of Great Britain in 1707 (later succeeded by the United Kingdom), the British Armed Forces have seen action in most major wars involving the world's great powers, including the Seven Years' War, the American War of Independence, the Napoleonic Wars, the Crimean War, the First World War and the Second World War. Britain's victories in most of these wars allowed it to influence world events and establish itself as one of the world's leading military and economic powers. The British Armed Forces consist of: the Royal Navy, a blue-water navy with a fleet of 66 commissioned ships, together with the Royal Marines, a highly specialised amphibious light infantry force; the British Army, the UK's principal land warfare branch; and the Royal Air Force, a technologically sophisticated air force with a diverse operational fleet consisting of both fixed-wing and rotary aircraft. The British Armed Forces include standing forces, Regular Reserve, Volunteer Reserves and Sponsored Reserves.

King Charles III, sovereign of the United Kingdom, is the Head of the Armed Forces, with officers and personnel swearing allegiance to him. Long-standing constitutional convention, however, has vested de facto executive authority, by the exercise of royal prerogative, in the Prime Minister and the secretary of state for defence. The Prime Minister (acting with the Cabinet) makes the key decisions on the use of the armed forces. The UK Parliament approves the continued existence of the British Army by passing an Armed Forces Act at least once every five years, as required by the Bill of Rights 1689. Only a "standing army" requires reapproval by Parliament; the Royal Navy, Royal Air Force and the Royal Marines and any other forces are not included in the requirement. The armed forces are managed by the Defence Council.

The United Kingdom is one of five recognised nuclear powers, a permanent member on the United Nations Security Council, a founding and leading member of NATO and party to the AUKUS security pact and the Five Power Defence Arrangements. Overseas garrisons and training facilities are maintained at Ascension Island, Bahrain, Belize, Bermuda, British Indian Ocean Territory, Brunei, Canada, Cyprus, the Falkland Islands, Germany, Gibraltar, Kenya, Montserrat, Nepal, Qatar, Singapore and the United States.
