Morosi (or Moorosi; died 20 November 1879) was a Baphuthi chief in the wild southern part of Basutoland. He led a revolt against the Cape Colony government in 1879, in defence of his independence south of the Orange River. The British refused to help the Cape Government. However, Letsie, the paramount chief and first son of Moshoeshoe, and many of the Sotho ruling establishment, rallied to support the Cape forces, and the rebellion was put down after several months of arduous fighting.
