Frances Villiers, Countess of Jersey was a British courtier and Lady of the Bedchamber, one of the more notorious of the many mistresses of King George IV when he was Prince of Wales, "a scintillating society woman, a heady mix of charm, beauty, and sarcasm".

Lady of the Bedchamber is the title of a lady-in-waiting holding the official position of personal attendant on a British queen regnant or queen consort. The position is traditionally held by the wife of a peer. A lady of the bedchamber would give instructions to the women of the bedchamber on what their queen wished them to do, or may carry out those duties herself.
