Tŝilhqox Biny (Pronounced: Tsyle-koh Bee), known as Chilko Lake, is a 180 km2 lake in west-central British Columbia, at the head of the Chilko River on the Chilcotin Plateau. The lake is about 65 km long, with a southwest arm 10 km long. It is one of the largest lakes by volume in the province because of its great depth, and the largest above 1,000 m in elevation. It and Harrison Lake are the largest lakes in the southern Coast Mountains.
On March 11, 2019, the Province of British Columbia, working with the Tŝilhqot’in National Government, officially changed the name of the lake from Chilko Lake to Tŝilhqox Biny.
