Major is a rank of commissioned officer, with corresponding ranks existing in almost every military in the world.

When used unhyphenated, in conjunction with no other indicator of rank, the term refers to the rank just senior to that of an Army captain and just below the rank of lieutenant colonel. It is considered the most junior of the field ranks. In some militaries, notably France, the rank is referred to as "Commandant", while in others it is known as "Captain-Major". It is also used in some police forces and other paramilitary rank structures.

When used in hyphenated or combined fashion, the term can also imply seniorty at other levels of rank, including "General-Major" or "Major General", denoting a mid-level general officer, and "Sergeant Major", denoting the most senior NCO of a military unit.
