Dioïla Cercle is an administrative subdivision of the Koulikoro Region of Mali.

It lies at the southeast corner of the region, and prior to 1977, it was combined with what is now Kati Cercle and the District of Bamako in the "Bamako Cercle", with the capital city as its seat.

The Dioïla Cercle is divided into 23 communes:[3][4] Dioïla Cercle is home to primarily Bambara and Malinke farmers, and formed part of the pre-colonial Bambara Empire.

There are also populations of Muslim Maraka, Fula, and Bozo fishing communities.

The Cercle falls largely south of the dryer Sahel land, in the wetter Sudan.
