Cottan-Bimbang National Park, Nature reserve in Mid-Coast Council, Australia.

Cottan-Bimbang National Park is a former state forest on the eastern escarpment, 443 km north of Sydney and 65 km south-east of Walcha. The Oxley Highway crosses it south of Werrikimbe National Park, and Myrtle Scrub Road forms a 15 km circuit in the west. Tall old-growth eucalypt forest and temperate rainforest grow here, with the walking stick palm in the rainforest.

Cottan-Bimbang was formerly a state forest and became a national park; the sources give no founding date. The change ended logging in the tall old-growth eucalypt forest and brought the rainforest and its walking stick palms under national park protection.

The name comes from an Aboriginal language and refers to a palm species that grows naturally in the warm rainforests here. You can spot these plants as you walk through the dense forest areas.

The Oxley Highway runs through the park and provides easy access from the main road. Visitors can use side roads to reach picnic areas and camping spots.

The park's name is the local Aboriginal word for the walking stick palm (Linospadix monostachyos), which grows in its temperate rainforests. Blackberries (Rubus) are also a serious weed problem here, an issue land managers work to control.
