Kano (Ajami: كَنُواْ) is a city in northern Nigeria and the capital of Kano State. It is the second largest city in Nigeria after Lagos, with over ten million citizens living within 449 km (173 sq mi). Located in the savanna, south of the Sahel, Kano is a major route of the trans-Saharan trade, having been a trade and human settlement for millennia. It is the traditional state of the Dabo dynasty who have ruled as emirs over the city-state since the 19th century. Kano Emirate Council is the current traditional institution inside the city boundaries of Kano, and under the authority of the Government of Kano State.

The city is one of the seven medieval Hausa kingdoms. The principal inhabitants of the city are the Hausa and Fulani people. Centuries before British colonization, Kano was strongly cosmopolitan with settled populations of Arab, Tuareg, Kanuri and remains so with the Hausa language spoken as a lingua-franca by over 70 million speakers in the region.

Islam arrived in the city in the 11th century or earlier primarily through the trans-Saharan trade. As a result, Kano became wealthy and the commercial nerve centre of the region and Northern Nigeria, and is still associated as the " centre of commerce ".
