The Gumbayngirr State Conservation Area is a protected conservation area located in the Mid North Coast region of New South Wales, in eastern Australia. The 2,561-hectare (6,330-acre) conservation area is situated west of Nambucca Heads and contains a sub–tropical jungle, known as the League Scrub. Another section of the park, formerly known was the Little Wonder State Forest, was protected from logging by a year long blockade in 1992.

Part of the reserve is situated on a basaltic bench, with relatively fertile red soils. Pumice can be seen on the forest floor, indicating previous volcanic activity. The altitude is 750 metres (2,460 ft) above sea level with a high rainfall. The rainforest has not been logged, and consists of a diverse jungle of 73 tree species, forming an impressive 40 metres (130 ft) canopy.

Significant tree species include Stinging Tree, Yellow Carabeen, Moreton Bay Fig, Small leaf fig, Black Booyong, Bonewood, Purple Cherry, Sour Cherry and Rose Maple.
