Lake Bolac is a town in the Western District region of Victoria, Australia.

Lake Bolac was the northern boundary of the Girai wurrung people's traditional lands, according to Norman Tindale, while large groups of up to 1,000 Djab wurrung and other peoples gathered here for a couple of months during the annual short-finned eel migration.

[2][3] George Augustus Robinson recorded in 1841 that 800 Aboriginal people had gathered at Lake Bolac – 'Lake Boloke' – to feast on plentiful eels, when "...local tribes numbered only sixty individuals".

[5] Anthropologist Harry Lourandos noted evidence of semi-permanent settlement near the lake.

[8] Lake Bolac is in the Western District region of Victoria, within the local government area of the Rural City of Ararat, 91 kilometres (57 mi) west of Ballarat.
