Departments of Ivory Coast (French: départements de Côte d'Ivoire) are currently the third-level administrative subdivision of the country. Each of the 31 second-level regions of Ivory Coast is divided into two or more departments. (The autonomous districts are containing departments, but have a specific status.) Each department is divided into two or more sub-prefectures. Since 2020, there are 111 departments of Ivory Coast.

Departments were first created in 1959. During their existence, they have been first-, second-, and third-level administrative subdivisions.

There are currently 111 departments of Ivory Coast. The departments are as follows:

Departments were established in 1961 and were the original first-level administrative subdivision of independent Ivory Coast. Initially, there were just four departments: Centre, Nord, Sud-Est, and Sud-Ouest. In 1963, two more departments were created: Est was created by dividing Sud-Est, and Centre-Ouest) was created by dividing Sud-Ouest. As a result of the divisions, Sud-Est was renamed Sud and Sud-Ouest was renamed Ouest.

In 1969, the six departments were abolished and in their place 24 new departments were created. The following table illustrates how the old departments were divided into the new departments:

Due to a lack of government resources, the 1969 changes were not fully implemented until 1974.

From 1974 onward, new departments were occasionally created through division of pre-existing departments. New departments were created in 1974 (2), 1980 (8), 1988 (15), and 1995 (1). In 1997, when there were 50 departments, regions were created, which supplanted departments as the first-level administrative subdivision. As a result, the 50 departments became second-level divisions.

More departments were created in 1998 (8), 2005 (12), 2008 (11), and 2009 (9). By the time of the late-2011 reorganisation of the subdivisions of Ivory Coast, there were 90 departments in 19 regions.
