The Royal Hamilton Amateur Dinghy Club (RHADC) is a private yacht club in the British Overseas Territory of Bermuda that was established as the Hamilton Amateur Dingey Association on, or before, 28 July 1882.

The Hamilton Amateur Dingey Association was created to promote the racing of dinghies, which in Bermuda meant the Bermuda Fitted Dinghy, a scaled down version of the traditional sloops used locally as work boats and yachts.

[4] In 1883, HRH Princess Louise, daughter of Queen Victoria, visited Bermuda, conferring the Royal title and donating a trophy that was awarded to the winner of a dinghy race held on 8 March, which was restricted to boats both owned and steered by club members.

A defaced White ensign was made for the club by Messrs. Lanff & Neeve, 97 Leadenhall Street, London.

A change in the rules for Royal titles was made in 1890, restricting the authority to grant these to the reigning Monarch.
