Hendrik Samuel Witbooi, Nama name: ǃNanseb ǂKharib ǃNansemab, (25 May 1865 – 16 October 1928) was the fourth Kaptein of the ǀKhowesin, a subtribe of the Orlam, in Gibeon in South-West Africa, today's Namibia. When during the Herero Wars his father Hendrik Witbooi fell he inherited the chieftaincy from him. He reigned until his death in 1928 when his brother David Witbooi succeeded him as Kaptein of the ǀKhowesin.
