The Norwegian Armed Forces ( Norwegian: Forsvaret , "The Defence") is the military organisation responsible for the defence of Norway. It consists of four branches, the Norwegian Army, the Royal Norwegian Navy, which includes the Coast Guard, the Royal Norwegian Air Force, and the Home Guard, as well as several joint departments.
The military force in peace time is around 16,048 personnel including military and civilian staff, and around 63,318 in total with the current military personell, conscripts and the Norwegian Home Guard in full mobilization.
The armed forces are subordinate to the Ministry of Defence, led by Frank Bakke Jensen. The formal commander-in-chief is King Harald V ; however, the de facto commander-in-chief is Chief of Defence Haakon Bruun-Hanssen. His staff is located at Akershus Fortress in Oslo, while the Norwegian Joint Headquarters, responsible for commanding operations, is located in Bodø. The main naval base is Haakonsvern in Bergen, the main army camps are in Bardu, Målselv and Rena, and the main air station is Ørland.
An organised military was first assembled in Norway in the 9th century and was early focused around naval warfare. The army was created in 1628 as part of Denmark–Norway, followed by two centuries of regular wars. A Norwegian military was established in 1814, but the military did not see combat until the German occupation of Norway in 1940. Norway abandoned its position as a neutral country in 1949 to become a founding member of the North Atlantic Treaty Organisation (NATO). The Cold War saw a large build-up of air stations and military bases, especially in Northern Norway. Since the 2000s, the military has transformed from a focus on defence from an invasion to a mobile force for international missions. Among European NATO members, the military expenditure of US$7.2 billion is the highest per capita.
The Chief of Defence (a four-star general or admiral) heads the armed forces, and is the principal military adviser to the Minister of Defence.

Other main structures, include:
- Defence Staff Norway (DEFSTNOR) in Oslo acts as the staff of the Chief of Defence. It is headed by a three-star general or admiral. DEFSTNOR assigns priorities, manages resources, provides force generation and support activities. Each of the four branches of defence is headed by a two-star general/admiral who are subordinate to DEFSTNOR.
- National Joint Headquarters (NJHQ) located at Reitan, close to Bodø has operational control of Norwegian armed forces worldwide 24/7. It is headed by the Supreme Commander Norwegian Forces – a three-star general or admiral.

Norway employs a weak form of mandatory military service for men and women. While 63,841 men and women were called in for the examination of persons liable for military service in 2012 (mandatory for men), 9265 were conscripted.  In 2015 conscription was extended to women making Norway the first NATO member and first European country to make national service compulsory for both men and women.  There is a right of conscientious objection.
