The Honourable Society of Knights of the Round Table, also known as The Knights of the Round Table Club, is a British society which exists to perpetuate the name and fame of King Arthur and the ideals for which he stood. It meets at the Lansdowne Club, Mayfair.

The society was formed in 1720 at the Fountain Coffee House, the site of the former Savoy Palace on London's Strand. Its membership was drawn from authors, actors, artists, and their patrons. Famous members included David Garrick, who was a member from 1761 to 1776, and Charles Dickens.
