Louis-Napoléon Chaltin (1857–1933) was a Belgian career soldier and colonial official notable for his service in the Congo Free State during the late 19th century.

He was appointed a lieutenant in the Belgian Army in 1885 and entered the service of the recently created Congo Free State in 1891.

[4] Chaltin secured the Dungu region in the northeast of the Free State and was commander of the Haut-Uélé district from 1893.

His forces were to advance first to the Lado Enclave on the Nile, which had been ceded to him but not yet occupied, and then northward towards Khartoum, capital of the declining Mahdist state of Sudan.

Dhanis's force was mainly made up of ethnic Tetela, who rebelled and killed several Belgian officers, then went on the region's rampage.
