Murnpeowie or Murnpeowie Station is a pastoral lease in outback South Australia. The pastoral lease once operated as a sheep station but now operates as a cattle station. The land occupying the extent of the pastoral lease was gazetted as a locality by the Government of South Australia on 26 April 2013 with the name 'Murnpeowie'.
It is located approximately 96 kilometres (60 mi) east of Marree and 102 kilometres (63 mi) north east of Lyndhurst. The area is composed of gibber plains that support dense stands Mitchell grass and saltbush.
The unusual name is Aboriginal in origin and means place of the Bronzewing Pigeon.
Leases in the area were taken up by John Baker in 1857 with more added through the 1860s. Baker was surrounded by leases held by Thomas Elder. When Baker died in 1872, Elder consolidated all of the runs into a single entity of approximately 4,000 square miles (10,360 km2) named Blanchewater Horse Station with a carrying capacity of 20,000 head. The homestead was constructed in the 1880s, the woolshed in 1890. Both buildings had stone walls and round iron roofs. By 1894 the station was shearing 106,000 sheep, yielding 2,400 bales of wool. In 1909 a total of 120,000 sheep were shorn at Murnpeowie. The Blanchewater Homestead Ruins are listed on both the South Australian Heritage Register and the former Register of the National Estate.
Boundary riders at the station discovered the Murnpeowie Meteorite in 1910. The 2,520 pounds (1,143 kg) stone was thought to be a rock until the men struck it with a hammer and were amazed by the bell-like sound they heard.
