The Luluabourg Constitution (French: Constitution de Luluabourg) was the second constitution of the Democratic Republic of the Congo. Functional from 1 August 1964 until November 1965, it was meant to replace the basic law (Loi Fondamentale) that had been provisionally enacted when independence was declared in 1960. Unlike its predecessor, the Luluabourg Constitution featured a strong executive presidency and carefully delineated federalism between the central government and the provinces. It also formalized the adoption of the name "Democratic Republic of the Congo", succeeding the name "Republic of the Congo".
