Danish Armed Forces (Danish: Forsvaret; Faroese: Danska verjan; Greenlandic: Illersuisut; lit. 'the Defence') is the unified armed forces of the Kingdom of Denmark charged with the defence of Denmark and its self-governing territories Greenland and the Faroe Islands. The military also promote Denmark's wider interests, support international peacekeeping efforts and provide humanitarian aid.

Since the creation of a standing military in 1510, the armed forces have seen action in many wars, most involving Sweden, but also involving the world's great powers, including the Thirty Years' War, the Great Northern War, and the Napoleonic Wars.

Today, the armed forces consists of: the Royal Danish Army, Denmark's principal land warfare branch; the Royal Danish Navy, a blue-water navy with a fleet of 20 commissioned ships; and the Royal Danish Air Force, an air force with an operational fleet consisting of both fixed-wing and rotary aircraft. The Defence also includes the Home Guard. Under the Danish Defence Law the Minister of Defence serves as the commander of Danish Defence (through the Chief of Defence and the Defence Command) and the Danish Home Guard (through the Home Guard Command). De facto the Danish Cabinet is the commanding authority of the Defence, though it cannot mobilize the armed forces, for purposes that are not strictly defence oriented, without the consent of parliament.
