Brigadier /brɪɡəˈdɪər/ is a military rank, the seniority of which depends on the country.

In some countries, it is a senior rank above colonel, equivalent to a brigadier general, typically commanding a brigade of several thousand men.

In other countries, it is a non-commissioned rank (e.g. Spain, Italy, France, the Netherlands and the Indonesian Police ranks).

In many countries, especially those formerly part of the British Empire, a brigadier is either the highest field rank or most junior general appointment, nominally commanding a brigade. It ranks above colonel and below major general.

The rank is used by the British Army, the Royal Marines, the Australian Army, the Indian Army, the Sri Lankan Army, the New Zealand Army, the Pakistan Army and several others. Although it is not always considered a general officer rank, it is always considered equivalent to the brigadier general and brigade general rank of other countries. In NATO forces, brigadier is OF-6 on the rank scale.
