The Azov Assault Brigade is a formation of the National Guard of Ukraine formerly based in Mariupol, in the coastal region of the Sea of Azov, from which it derives its name. It was founded in May 2014 as the Azov Battalion, a self-funded volunteer militia under the command of Andriy Biletsky, to fight Russian-backed forces in the Donbas War. It was formally incorporated into the National Guard on 11 November 2014, and redesignated Special Operations Detachment "Azov", also known as the Azov Regiment. In February 2023, the Ukrainian Ministry of Internal Affairs announced that Azov was to be expanded as a brigade of the new Offensive Guard.

Andriy Yevheniyovych Biletsky is a Ukrainian far-right politician. He is the leader of political party National Corps. He was the first commander of the volunteer militia Azov Battalion, which he founded in 2014, and a co-founder of the nationalist movement Social-National Assembly. From 2014 until 2019, Biletsky was a People's Deputy of Ukraine.
