Witotoan (also Huitotoan or Uitotoan, occasionally known as Huitoto–Ocaina to distinguish it from Bora–Witoto) is a small language family of southeastern Colombia (Amazonas Department) and the neighbouring region of Peru.
Aschmann (1993) proposed that the Boran and Witotoan language families were related, in a Bora–Witoto stock.
Jolkesky (2016) notes that there are lexical similarities with the Pijao, Yaruro, Arawak, Bora-Muinane, Choko, and Tukano language families due to contact.
Some of this contact had occurred due to the expansion of Witotoan speakers down the Putumayo River.
The following extinct languages are unclassified within Witotoan: Kaufman (2007) adds Andoque.
