The District of Orientale Province was created from Stanley Falls District on 15 July 1898. The district was expanded to become Orientale Province in 1913. It was divided in 1933 into Costermansville (later Kivu) and Stanleyville Province. Stanleyville Province was renamed Orientale Province from 1947 to 1963, when it was broken up into Kibali-Ituri, Uélé and Haut-Congo provinces. Orientale Province was reconstituted in 1966. Between 1971 and 1997 it was called Haut-Zaïre, then it returned to the name of Orientale. The province contained the Bas-Uele, Haut-Uele, Ituri and Tshopo districts. These were elevated to provinces in 2015 under the 2006 constitution.

The province lay in the northeast of the country. Originally it bordered Équateur to the west, Congo-Kasaï to the southwest and Katanga to the south. After being reduced in size, it bordered Équateur to the west, Kasaï-Oriental province to the southwest, Maniema to the south, and North Kivu to the southeast. It also bordered the Central African Republic and South Sudan to the north, and Uganda to the east. The provincial capital was Stanleyville, later renamed Kisangani.

On 15 July 1898 the Stanley Falls District became the District of Orientale Province (District de la province Orientale), with Stanleyville as its headquarters.^[1] The Lualaba District in the south was split off at this time. The district was also called Stanleyville District. In 1910 the new vice-government general of Katanga was formed the south, with parts of Lualaba District and parts of Stanleyville.^[2]

Orientale/Oost Province was formed in 1913 in the Belgian Congo from the District of Orientale Province, expanded to include Haut-Uélé, Bas-Uélé and Aruwimi. The new province contained the districts of Bas-Uele, Haut-Uele, Ituri, Stanleyville, Aruwimi, Maniema, Lowa and Kivu. It was divided in 1933 into Costermansville (later Kivu) and Stanleyville Province. Stanleyville Province was renamed Orientale/Oost Province from 1947 to 1963, when it was broken up into Kibali-Ituri, Uélé and Haut-Congo provinces. Orientale Province was reconstituted in 1966 from the amalgamation of the Uele, Kibali-Ituri and Haut-Congo provinces. In 2015 it was dissolved into the provinces of Bas-Uélé, Haut-Uélé, Ituri and Tshopo.

In 1998 the Orientale villages of Durba and Watsa were the center of an outbreak of Marburg virus disease among gold mine workers.

The Ituri district of Orientale was the scene of the Ituri conflict.

As of 2014, militia groups continue to fight in the province and have reportedly committed many atrocities against the local population, such as forcing women into sex slavery and forcing men to work in mines.^[3]

The province was divided into the city of Kisangani and the districts of Bas-Uele, Haut-Uele, Ituri and Tshopo. Cities and towns, with their 2010 populations, are:
