Yaringa Marina (also known as Yaringa Boat Harbour) is a full-service boating facility situated on Watson Creek on the Mornington Peninsula, within an hour's drive of Melbourne.

It sits at the edge of Yaringa Marine National Park, Victoria's smallest marine national park, which occupies a sheltered corner of Western Port at Watson Inlet.

The marina serves as a practical gateway to Western Port's waters, which are internationally recognised for their mangrove communities, saltmarsh habitats, seagrass beds, and migratory shorebird populations under the Ramsar Convention.

The surrounding waterways and Yaringa Marine National Park are accessible only by boat, making the marina a key access point for those looking to explore this ecologically significant area by kayak, canoe, or powerboat.
