Lake Connewarre (Aboriginal Wathawurrung language: Kunawarr keelingk[2] literally meaning black swan lake), a shallow estuarine 880-hectare (2,200-acre) lake on the Barwon River, is located on the Bellarine Peninsula southeast of Geelong in the Australian state of Victoria.

Lake Connewarre forms part of the Port Phillip Bay (Western Shoreline) and Bellarine Peninsula Ramsar Site as a wetland of international importance, with much of the wetland area also part of the Lake Connewarre State Game Reserve.

However, most of the land surrounding Lake Connewarre has been cleared for agricultural purposes resulting in environmental degradation.

[4] The lake is shallow being less than one metre in depth and generally unsuitable for boating.

The lake and its associated wetlands are part of the Bellarine Wetlands Important Bird Area because of its conservation significance for several species of waders, waterbirds and the orange-bellied parrot.
