Manly Boat Harbour is a recreational maritime hub located in the coastal suburb of Manly, Queensland, on the eastern shore of Brisbane along Moreton Bay.

Frequently cited as one of the largest boat harbours in the Southern Hemisphere, it accommodates over 1,500 vessels across several marinas, including the Royal Queensland Yacht Squadron and East Coast Marina.

The harbour sits at approximately 27°27'S, 153°11'E, roughly 40 nautical miles from the Gold Coast Seaway. The harbour is a popular access point for recreational boating and yachting in the Moreton Bay region.

It is also noted as a rewarding photography location, particularly at sunrise, when calm water produces strong reflections off the moored boats. Parking is available directly adjacent to the waterfront.
