Winninowie is a locality in the Mid North of South Australia.

[3] Winninowie is 21 kilometres (13 mi) southeast of Port Augusta,[4] on the plain between Spencer Gulf on the west and the southern Flinders Ranges on the east.

A railway siding at Winninowie opened with the line in 1936; a crossing loop remains there today.

[6] The boundaries for the locality were first created in 1994 for the long established local name; initially, they only comprised the section within the City of Port Augusta, with the Mount Remarkable section being added in 1997.

The name was derived from the Hundred of Winninowie, which in turn stemmed from a word of Aboriginal origin.
