Lulonga District (, ) was a district of the Belgian Congo created in 1912 and dissolved in 1933. Today part of Lulonga is in the current province of ÃÂquateur, and part in the province of Tshuapa.
Lulonga District was created on 28 March 1912 when an arrêté royal divided the Congo into 22 districts. On this date the ÃÂquateur District was divided, with the south becoming a smaller ÃÂquateur District and the north becoming Lulonga District. The district is named after the Lulonga River, a left tributary of the Congo River. A map of the colony in 1912 shows Lulonga bordering the smaller ÃÂquateur District to the south, Bangala District to the west and north, and Aruwimi District to the east. A map of 1926 shows somewhat different boundaries.
ÃÂquateur Province was created in 1917. As of 1926 the province included the districts of Ubangi, Bangala, Lulonga, ÃÂquateur and Lac Léopold II. With the reorganization of 1933, Lulonga District was merged into ÃÂquateur District to form Tshuapa District in the new Coquilhatville Province. Coquilhatville Province was renamed ÃÂquateur Province in 1947.
On 11 July 2015 ÃÂquateur Province was divided into the current much smaller Province of ÃÂquateur, and the provinces of Mongala, Nord-Ubangi, Sud-Ubangi, and Tshuapa.
