Nuyts Reef Conservation Park is a protected area in the Australian state of South Australia associated with Nuyts Reef, which is located off the state's west coast in the Great Australian Bight about 29 kilometres (18 miles) west south-west of Fowlers Bay.

[3] This was reconstituted as Nuyts Reef Conservation Park on 27 April 1972 under the National Parks and Wildlife Act 1972 to "conserve Australian sea lion breeding habitat".

[4] In 1980, the conservation park was described as follows:[8] A group of five small reefs supporting an Australian sea lion colony and providing breeding habitat for seabirds... Five small granite reefs and rocks, some of which are swept by storm waves.

Isolation and the absence of introduced species has ensured habitat preservation.

The conservation park including its marine zone is classified as an International Union for Conservation of Nature (IUCN) Category Ia protected area.
