Rockingham Lakes Regional Park, Nature reserve in City of Rockingham, Australia.

Rockingham Lakes Regional Park is a non-continuous conservation park of 4,270 hectares about 40 kilometres south of Perth, within the City of Rockingham. It holds remnants of the Swan Coastal Plain and two threatened ecological communities, thrombolites and sedgelands. Cape Peron and Lake Richmond form an isolated north-western block; Anstey and Paganoni Swamp a separate southern part.

The idea of regional parks in Western Australia dates to the 1955 Stephenson-Hepburn Report, which proposed reserving private land for public use. The Environmental Protection Authority identified areas of conservation value in 1983, and in 1989 the state government gave the Department of Conservation and Land Management responsibility for managing regional parks. Rockingham Lakes Regional Park was announced in 1997.

The park's name comes from the lakes within it, and the City of Rockingham manages it with the state. Visitors can see thrombolites at Lake Richmond, living limestone structures built by microbes, and the park is one of eleven regional parks in the Perth region. The park also contains two threatened ecological communities: thrombolites and sedgelands.

Wear sturdy footwear and prepare for coastal weather conditions, as the terrain can be exposed and windy. Different park sections can be visited based on your available time and walking preferences.

Lake Richmond holds living thrombolites, microbial limestone structures that grow in shallow water and are one of two threatened ecological communities in the park. The park also keeps evidence of sea level changes over the past 7,000 years.
