Stanley Bridge Harbour is a federally owned marina and harbour facility located in Stanley Bridge, Prince Edward Island, managed by the Stanley Bridge Harbour Authority — a not-for-profit organization operating under a lease with Fisheries and Oceans Canada since 1996.

The harbour was significantly expanded in 2016–17 to better serve recreational boaters and visitors.

Improvements included a new breakwater, 60-plus boat slips, updated electrical and wastewater services, new retail space, boardwalks, washrooms, lockers, showers, and improved parking and access.

The volunteer board of up to nine directors oversees operations year-round.
