Port of Poole Marina opened in June 2011 as Poole Harbour's newest marina, representing a £1 million investment by Poole Harbour Commissioners.

It sits at the head of the Little Channel, approximately 250 metres eastward of the Stakes south cardinal buoy, with direct access from that channel. The marina frequently serves as an overflow for its sister facility, Poole Quay Yacht Haven.

The marina can accommodate up to 75 vessels on an annual basis, with long-term berths available for vessels up to 20 metres in length. Visiting vessels of up to 50 metres can be accommodated by prior arrangement.

It enjoys views over Brownsea Island and the Purbeck Hills, and sits within easy walking distance of Poole Quay.
