Waychinicup National Park, Nature reserve near Albany, Australia

Waychinicup National Park covers 40 square kilometres of the Western Australian south coast, 65 kilometres east of Albany, between Normans Beach and Cheynes Beach. Its coastline runs from rugged Southern Ocean shore to boulder-strewn hilltops, with tree-filled, deeply incised valleys where freshwater streams run over moss-covered boulders. The Waychinicup River meets the ocean at an inlet beside the camping area.

The park lies within the Two Peoples Bay and Mount Manypeaks Important Bird Area, identified by BirdLife International for its role in conserving rare birds. In 1983, 14 noisy scrub-birds were translocated here from Two Peoples Bay Nature Reserve, followed by 16 more in 1985; by 1994, 223 singing males were counted. In 2010 an insurance population of Gilbert's potoroo was placed in an enclosure, but carpet pythons entered and preyed on the marsupials; by December 2018, 20 remained, a fifth of the world population.

The name Waychinicup combines the Nyoongar word for emu with a suffix meaning place, a reminder that this stretch of coast lies within Menang Noongar country. Visitors today notice the mix of heath and granite rather than any built heritage; the park's cultural life is tied to the wildlife, with quendas often seen by day along the tracks and the Mount Gardner area holding western ringtail possums whose nests of small twigs are about the size of a basketball.

Access is via the South Coast Highway and then a gravel track that is often impassable after bad weather. The camping area and bush toilet sit near the inlet of the Waychinicup River. The park lies 65 km east of Albany, with coastline running between Normans Beach and Cheynes Beach.

In 2010 an insurance population of Gilbert's potoroo was placed in an enclosure here; by 2015 native carpet pythons were getting in and preying on the marsupials. By December 2018 the park held 20 of these critically endangered animals, a fifth of the world population. Fourteen noisy scrub-birds were moved here from Two Peoples Bay in 1983, sixteen more in 1985.
