Ousmane Coulibaly (born 9 July 1989) is a French-born Malian professional football player. Currently, he is a Free Agent. His brother is the professional kickboxer, multiple champion of France and world champion, Abdarhmane Coulibaly.
In August 2014, Coulibaly signed a three year-contract with Superleague side Platanias for an undisclosed fee. He played exceptionally well for two consecutive years, therefore was monitored by several Greek top clubs, as well as German and English clubs.
On 30 August 2016, Coulibaly moved to Panathinaikos for an estimated amount of €250.000 signing a three-season contract with the club. He was expected to be the backup of experienced Italian Giandomenico Mesto. On 11 January 2018, Mechelen filed an offer to the financially struggling Greens for the acquisition of Coulibaly in the range of €200.000. The player asked to be excluded from the first-team squad on 16 April 2018 due to Panathinaikos being in a dire financial and administrative state, and two weeks later, he filed an official request to leave Panathinaikos on a free transfer.
