Cottan-Bimbang is a national park in New South Wales, Australia, 443 km[1] north of Sydney and 65 km south east of Walcha and was formerly a state forest.

Myrtle Scrub Road is a 15-kilometre circuit in the west of the park that connects with the Oxley Highway.

This park is situated on the eastern escarpment with extensive tall old-growth eucalypt forest, rainforest, threatened frog species, yellow-bellied gliders (Petaurus australis) and koalas.

'Cottan-bimbang' is the local Aboriginal word for the walking stick palm (Linospadix monostachya), which grows in the park's temperate rainforests.

There is a cleared area for camping at Maxwells Flat on the Causeway Road, and a long drop toilet.
