Exercise Joint Warrior is a major biannual multi-national military exercise which takes place in the United Kingdom, predominately in north west Scotland. It is the successor of the Neptune Warrior exercises and Joint Maritime Course. Joint Warrior is organised by the UK Ministry of Defence and is Europe's largest military exercise and can involve up to 13,000 military personnel, from all three British armed forces, NATO and other allied countries.

Operations include airborne assaults, amphibious landings and training in counter-insurgency, counter-piracy and interstate war. Live-fire exercises take place on various weapons ranges. Joint Warrior exercises take place in the spring and autumn and have a duration of two weeks.

More recently, JMC exercises took place three times a year, in spring, summer and winter. In 2006 the exercise was re-branded as Neptune Warrior and in 2007 was reduced to two events per year. In 2008 the Joint Warrior name was introduced to reflect the increasing involvement of all three military branches. Each exercise is identified by the last two digits of the year it takes place and a number 1 or 2 depending on whether it is the first or second exercise of the year. For example, JMC 98/1 was the first Joint Maritime Course of 1998 and JW 15/2 was the second Joint Warrior exercise of 2015.
