The Belgian Minister of the Colonies (French: Ministre des Colonies, Dutch: Minister van Koloniën) was a Belgian parliamentarian who was responsible for the territories of the colonial empire in Central Africa from 1908 to 1962, comprising the colony of the Belgian Congo (1908–60) and the international mandate of Ruanda-Urundi (1916–62).

For most of the existence of the post, office holders were known as "Minister of the Colonies" (Ministre des Colonies or Minister van Koloniën).

From the accession of Maurits Van Hemelrijck [nl] in November 1958, however, the ministerial title changed to "Minister of the Belgian Congo and Ruanda-Urundi" (Ministre du Congo belge et du Ruanda-Urundi or Minister van Belgisch-Congo en Ruanda-Urundi).

[1] On 30 June 1960, with the independence of the Belgian Congo, the title changed to "Minister of African Affairs" (Ministre des affaires africaines or Minister van afrikaanse zaken) whose only office holders were August de Schryver and Harold Charles d'Aspremont Lynden.

Raymond Scheyven was "Minister without portfolio, charged with the economic and financial affairs of the Belgian Congo and Ruanda-Urundi"[a] while Walter Ganshof van der Meersch was "Minister without portfolio, charged with general affairs in Africa".
