Gciriku or Dciriku (Diriku) or Dirico (in Angola), also known as Manyo or Rumanyo, is a Bantu language spoken by 305,000 people along the Okavango River in Namibia, where it is a national language, in Botswana, and in Angola. It was first known in the west via the Vagciriku, who had migrated from the main Vamanyo area and spoke Rugciriku, a dialect of Rumanyo. The name Gciriku (Dciriku, Diriku) remains common in the literature, but within Namibia the name Rumanyo has been revived. The Mbogedu dialect is extinct; Maho (2009) lists it as a distinct language, and notes that the names 'Manyo' and 'Rumanyo' are inappropriate for it.
