Damboa is a Local Government Area of Borno State, Nigeria. Its headquarters are in the town of Damboa. It has an area of 6,219 km² and had a population of 233,200 at the 2006 census.

 The original settlers of Damboa are the Marghi people, but due to the booming economy of Damboa in the Calabash farming business during this period made many Kanuri people keep travelling to and fro to Damboa in the first place and later end up settling and marrying in Damboa at a later stage. As a result many of the Damboa people end up becoming half Kanuri and Half Marghi although there are still pure Marghi family as well as pure Kanuri family even as at today. This cultural assimilation brought a little discrepancies among the indigenous of Damboa because some people in Damboa prefers to be identified as Marghi while some other ones preferred to be identified as Kanuris, but the truth is that Damboa composed of Marghi majority and Kanuri minority in the town settle at the Local Government Area.
