The Mitsogo or Tsogo are an ethno-cultural group from the highlands of Gabon. They reside mainly in Ngounié Province to the north and east of Mouila.  They speak the Tsogo language. In the late 19th and early 20th century they were known for their fierce resistance to the French. 

Like the Fang and Kota peoples who live to the north and the Punu who live to the south, the Mitsogo carve figures whose primary purpose is to guard the relics of ancestors. They also practice bwiti, which is an observed practice of various other peoples throughout Gabon.
