Hendrik Samuel Witbooi

Captain Hendrik Samuel Witbooi (; 1 June 1906 – 29 July 1978) was the sixth Kaptein of the ǀKhowesin, a subtribe of the Orlam, in the area of South West Africa (SWA), today's Namibia. He was born in Gibeon; Hendrik Witbooi was his grandfather. He was selected to be the successor of his uncle David Witbooi who died in 1955.

Together with Hosea Kutako, Samuel Witbooi was involved in the drafting of a petition to the United Nations in 1947 to put Namibia under British trusteeship. The petition was signed at the occasion of the 1947 Herero Day gathering and subsequently presented to the UN by Reverend Michael Scott, because neither Kutako nor Witbooi were allowed to leave South West African territory. In 1956, Witbooi addressed the UN again, "on behalf of the non-European inhabitants of SWA". The results were that the UN rejected a request to divide South West Africa and allocate its southern parts permanently to South Africa.
