Lac-Chicobi (French pronunciation: [lak ʃikɔbi]) is an unorganized territory in the Canadian province of Quebec, located within the Abitibi Regional County Municipality.

The area consists of two non-contiguous portions on either side of the incorporated municipality of Berry.

[3] The eponymous Lake Chicobi is roughly in the centre of the territory's western portion.

The lake's name, in the past also spelled as Chikobi, Chikobee, and Cikobi, comes from a First Nations word meaning "where there are no islands".

It is named after the geographic township of Guyenne (proclaimed in 1916), in turn named for the Régiment de Guyenne that fought under General Montcalm's command.
