Dimbokro Department was created in 1969 as one of the 24 new departments that were created to take the place of the six departments that were being abolished. It was created from territory that was formerly part of Centre Department. Using current boundaries as a reference, from 1969 to 1980 the department encompassed the following territory: all of Moronou Region; all of N'Zi Region; and Daoukro and Ouellé Departments in Iffou Region.
In 1980, Dimbokro Department was divided to create Bongouanou Department.[3] What remained was divided again in 1988 to create Daoukro Department.[3] In 1997, regions were introduced as new first-level subdivisions of Ivory Coast; as a result, all departments were converted into second-level subdivisions. Dimbokro Department was included in N'Zi-Comoé Region. In 1998, the department was divided again to create Bocanda Department.[3]
In 2011, districts were introduced as new first-level subdivisions of Ivory Coast. At the same time, regions were reorganised and became second-level subdivisions and all departments were converted into third-level subdivisions. At this time, Dimbokro Department became part of N'Zi Region in Lacs District.
