Nyam-Niam, a negro tribe in N. central Africa, whose territory extends from lat. 4° to 6° N., and from Ion. 24° to 29° E., and is bounded N. by the country of the Bongos, E. by that of the Mittoos, S. by that of the Monbuttoos, and W. by various tribes whose names are unknown. The first information respecting this tribe was given in 1859 by Petherick, and in 1863 by the Italian Piaggia; but Schwein-furth in 1870 was the first to traverse a large portion of the country. The Nyam-Nyam are cannibals, but in some respects more civilized than the neighboring tribes. They appear to have taken possession of their present country at a comparatively recent period, after conquering several other tribes. They live in conical straw huts, there being separate ones for men and women. The chiefs or sultans, of whom there are about 100, have very extensive powers over their subjects. Every settlement has a divan or bancajo, in which public affairs are discussed and decided, and where the boys are accustomed to stay from their eighth year.

The Nyam-Nyam show considerable skill in manufacturing earthen and iron ware, especially in the forging of weapons.
