George IV of the United Kingdom has been depicted many times in popular culture.
George IV appears as a character in Rodney Stone by Arthur Conan Doyle (1896), where he is shown as an irresponsible spendthrift, wildly self-indulgent and given to self-delusion, but not without some kindly impulses.
In Bernard Cornwell's novel Sharpe's Regiment, which is set during the Regency period, he is portrayed as fat, extravagant and possibly suffering from the same insanity which had afflicted his father. He is an enthusiastic fan of Richard Sharpe's military exploits, and claims to have been present at the Battle of Talavera and to have helped Sharpe capture a French standard. In the novel's historical note, Cornwell said he based the remark on an historical incident when George, during a dinner party at which Wellington was present, claimed to have led a charge at Waterloo.
George IV appears as a character in The Regency, Volume 13 of The Morland Dynasty, a series of historical novels by author Cynthia Harrod-Eagles. The fictional Lucy Morland, Countess of Aylesbury, is one of his 'set' and his reign and regency provide the backdrop to the novel.
Bernard Bastable's Dead, Mr. Mozart (1995) is a detective novel whose main character is an alternate version of Wolfgang Mozart who survives in the 1820s and has settled in England. The story's main crisis is that odd circumstances have drawn Mozart into damage control duty to prevent further eruption of the enmity between King George IV and Caroline of Brunswick immediately following the old king's death.
