Stanley Bridge Harbour sits on the Stanley River in Stanley Bridge, Prince Edward Island, where it widens toward New London Bay.

Managed by the Stanley Bridge Harbour Authority — a not-for-profit organization operating under a lease with Fisheries and Oceans Canada — the harbour serves both commercial fishing vessels and recreational boaters.

A boat launch provides access to the river, which offers calm upriver cruising past farmland, cottages, and mussel aquaculture operations, as well as open-water access to New London Bay.

The harbour was expanded in 2016–17 to better accommodate recreational boaters, with a new breakwater, updated slips, and improved infrastructure. The marina now offers more than 60 slips for vessels up to 50 feet, along with a boat ramp for trailered craft.

Its location near Cavendish makes it a popular destination for both local boaters and visitors exploring the island by water.
