Big Brook Arboretum Campground is a small, bookings-essential campsite located within Big Brook State Forest in Western Australia, roughly 3 km from the main recreation area at Big Brook Dam and about 10 km north of Pemberton.

It sits among the exotic trees of the Big Brook Arboretum and is accessible via the Karri Forest Explorer Drive or the long-distance Bibbulmun Track, which passes directly through the arboretum.

The campground accommodates tents, campervans, camper trailers, and caravans. Dogs are welcome provided they are kept on a leash. No park entry fee applies, though camping fees are charged.

The surrounding state forest offers bushwalking, swimming, fishing, and canoeing at Big Brook Dam, as well as the chance to explore notable trees including a 300-year-old karri known as "Big Karri."
