Royal Harbour Marina (Outer) is an access point within Ramsgate's Royal Harbour in Kent, the only harbour in the United Kingdom granted the right to use the "Royal" designation, a title bestowed by King George IV in 1821.

The outer harbour offers tide-independent, 24-hour access, making it a practical and flexible entry point for visiting pleasure craft and sailors. Together with the inner harbour, the site provides over 700 berths in total.

Designated a Heritage Harbour in 2024, it combines its historic maritime character with facilities serving both visitors and permanent berth holders, including commercial vessels and small boat owners.
