Manasse ǃNoreseb Gamab (also Manasse of Hoachanas, circa 1840–1 December 1905) was the thirteenth Kaptein of the Khaiǁkhaun (Red Nation), a subtribe of the Nama people in Namibia, between 1880 and 1905. At the start of Imperial Germany's colonisation of South-West Africa, Manasse was one of the most powerful leaders in the area.
