Nonkon is a small town and commune in the Cercle of Kolokani in the Koulikoro Region of south-western Mali. As of 2010 the commune (made of 20 villages) had a population of 9987.
The people of Nonkon trace their ancestry to NâÂÂTontji Diarra, originally from Koblé, near Gouni on the right bank of the Niger River, opposite Koulikoro. In a fit of anger, NâÂÂTontji killed the dog of his master and had to flee. He crossed the river with a friend and they were welcomed in Bélédougou by the village chief of Korian. They first established NâÂÂTontjibougou and later settled in a secluded valley founding the village of Nonkon.
In 1875, Nonkon successfully resisted an attack by the Toucouleur warriors of the Ahmadou Tall, son of El Hadj Umar Tall.
