Birni-N'Konni (also Birnin-Konni or shortened to Konni/Bkonni) is a town in the Tahoua Region of Niger, lying immediately north of the border of Nigeria and west of seasonal Maggia River. It is an important market town and transport hub and as of the 2012 census had a population of 63,169. The town is the historic centre of the small pre-colonial Hausa state of Konni. The name comes from the Hausa for "Walled Town of Konni", and many Hausa towns (such as Zinder) designate the old citadel neighbourhood the "Birni".Konni is known for its vernacular architecture including traditional granaries and is regarded as a centre for smuggling between Niger and Nigeria. Birni-N'Konni's contemporary importance rests on the surrounding agricultural lands and its place on the N1 highway, the main east-west highway linking Niger's capital Niamey and the nation's main eastern cities of Maradi and Zinder.
