Lake Muir is a freshwater lake, with a larger surrounding wetlands area, that is located in the South West region of Western Australia. The lake lies near Muirs Highway, north of Walpole and southeast of Manjimup.

Lake Muir was named after brothers Thomas and John Muir, the first European settlers in the Warren district, who settled at Deeside, 25 kilometres (16 mi) west of the lake, in 1852 and built a rush hut there in 1856.Historically the area was a Game Reserve, with a duck shooting season.The Department of Environment and Conservation (CALM) started monitoring the wetlands system in 1980 in order to manage the duck shooting.

On 5 January 2001, a 106-square-kilometre (41 sq mi) area was designated, under the Ramsar Convention as Ramsar site 1050, a wetland of international importance, acknowledging its rich ecological diversity.

A magnitude 5.7 earthquake was centred at the lake on 16 September 2018 and was followed by a magnitude 4.7 quake on 13 October and a 5.4 quake on 9 November.
