Chinaman's Hat (Port Phillip)

Chinaman's Hat is a small, artificial island in Port Phillip, near Melbourne, Victoria, Australia. The island was constructed in the late 1880s to serve as a navigation beacon. Its primary purpose was to warn ships of the shallow water of the Pope's Eye Shoal. The structure is essentially a circular platform of bluestone rock, surrounded by a timber fence.

The structure gained its colloquial name, "Chinaman's Hat," due to its resemblance to a traditional conical Asian hat when viewed from a distance. The name is considered by some to be culturally insensitive, although it remains in common usage and historical records.

The island is uninhabited, although it is sometimes used by seabirds. It is located within the Port Phillip Heads Marine National Park and is considered a significant historical and environmental site. Access to the island is generally restricted.
