Justin Kokolo-Longo (1913 – 21 November 1960) was a Congolese military officer who briefly served as deputy chief of staff of the Armée Nationale Congolaise.

[3][a] Kokolo maintained close connections with President Joseph Kasa-Vubu, a fellow Mukongo, who sought his protection from undisciplined troops.

[5] On 8 July 1960 Kokolo, as the most senior of the adjutants, was appointed by the Congolese government to be commander of the Camp Léopold II garrison.

However, that evening the provincial government seceded from the Congo and Kokolo was immediately expelled from its territory upon his arrival.

[7] On 21 November Kokolo attempted to force his way into the Ghanaian embassy in Léopoldville to carry out an extradition order against the chargé d'affaires.
