Murtoa is a wheat district town in Victoria situated around Lake Marma on the Wimmera Highway. At the 2006 census, Murtoa had a population of 912.
The name Murtoa is believed to come from a local Aboriginal word meaning "home of the lizard". Murtoa's post office opened on 1 August 1874.
The working section of the present day Murtoa Grain Receival Centre can hold up to 400,000 tonnes of grain.
Murtoa's Lake Marma, situated in the centre of town, has always been a haven for wildlife and one of the most attractive lakes in the Wimmera. It is currently being improved with restored surrounds. A main feature is the 120 year-old avenues of sugar gum trees around most of the lake. There is a playground, BBQ, Rotunda and large lawned areas adjacent. Rabl park immediately to the North of Lake Marma is a series of waterways and ponds with attractive treed surrounds. It also incorporates a Skate Park, playground, 1896 Railway's walking bridge, BBQ and large grassed areas. Both Lakes are great fishing and recreational areas, with abundant birdlife and made walking tracks surrounding both.
