Deepwater is a locality in the Australian state of South Australia located in the state’s south-east about 190 kilometres (120 mi) south-east of the state capital of Adelaide and about 104 kilometres (65 mi) south-east of the municipal seat in Tailem Bend.

Some land in the north which is occupied by the Messent Conservation Park is zoned for ‘conservation’.
