Kainuu brigade (; ) is a Finnish Army unit situated in Kajaani. The brigade is one of the biggest army units, training approximately 4000 conscripts annually. The Kainuu Brigade is one of the three readiness brigades in the Finnish Army.
The Brigade trains units suited for combat on the heavy snow and poor road-infrastructure areas of Northern Finland, and has several variations from normal Finnish Army training schedules and equipment to meet these demands, such as the light tracked all-terrain vehicles used for fast transportation of troops especially during wintertime.
The honorary march of the brigade is Hurtti-Ukko by Carl Collan.
