Lake Buloke is a eutrophic lake in the Wimmera region of north-western Victoria, Australia. The lake is fed by the Richardson River and is located adjacent to the township of Donald. In the indigenous Jardwadjali language, the river is named Banyenong, with banye meaning the "burning of roots and stumps" and nong meaning "the past;" and also named Buluk, meaning "lake." In the 1870s, the lake was known as Lake Banyenong, as buloke was a word meaning lake. The Shire of Buloke derives its name from the lake.
