Mundiwindi is a ghost town in the Pilbara region of Western Australia.

[2] The town housed employees of the Postmaster-General's Department responsible for the maintenance of the station, and their families.

The only buildings on site were "the Post Office, an engine room, a trunkline equipment building, a pump house (good quality water came from a bore) and a line depot".

At the time [1964] the complete population of Mundiwindi comprised the Guthrie family [Tom, a Senior Technician, and his wife, and their children, Stephen, Sharon, Tommy and David], District Line Officer Fred Atkins and his wife, who was the Postmistress and Lineman Bill Wright and his wife and sixteen-month-old daughter, Michelle.

Mr and Mrs Atkins had been three years at the old Mundiwindi Station which is about seven miles south, and three years at the present site.In 1973 the town was hit by Tropical Cyclone Kerry, causing some damage to buildings.
