Eva Valley is a rural locality in the Coomalie Shire, Northern Territory, Australia. It is located approximately 10 kilometres (6.2 mi) southwest of the town of Batchelor and 110 kilometres (68 mi) south of the Territory capital Darwin.

The locality was originally a large property known as Banyan Farm, but it was sold to the Childs family during the 1960s and renamed Eva Valley after one of the new owners, Eva Childs. The name has been retained with the subdivision of the area.
