Benwerrin is a rural locality in the Surf Coast Shire,
Victoria, Australia.

The vast majority of the Benwerrin locality is today
located within the Great Otway National Park and
Otway Forest Park. The Deans Marsh-Lorne Road
and the Benwerrin-Mount Sabine Road are the
only two roads through the area. Benwerrin
includes sections of the Erskine River and the
Stony Creek; the well-known Erskine Falls in
neighbouring Lorne lie close to the border with
Benwerrin.
