Caroline Agnes Graham, Duchess of Montrose (née Beresford; 21 August 1818 – 16 November 1894), styled Dowager Duchess of Montrose after 1874, was a notable British racehorse owner, aristocrat, and socialite.

She was described as a "wildly extravagant woman" who "strode across the racing scene",^[1] and was popularly known as the "Red Duchess", from both her scarlet racing colours and her habit of dressing from head to foot in that colour at race meetings.^[2] It was said of her in one of her obituaries that "few women in England create more stir in all classes of society".^[3] She betted heavily, hardly ever missed attending a race meeting where her horses were competing, and associated almost exclusively with followers of the turf.^[4]
