Margot Did (foaled 17 March 2008) is an Irish-bred, British-trained Thoroughbred racehorse and broodmare. After being sold cheaply as a yearling and again as a two-year-old she entered training with Michael Bell at Newmarket. As a juvenile in 2010 she showed high-class form, winning twice and finished second in the Albany Stakes, Princess Margaret Stakes and Lowther Stakes. In 2012 she was beaten in her first two races but established herself as a potentially high-class sprinter with wins in the Scurry Stakes and the Land O'Burns Fillies' Stakes. At York Racecourse in August she recorded her biggest win with a 20/1 upset victory in the Nunthorpe Stakes. She never reproduced her best form thereafter and finished unplaced in her five remaining races. She was retired from racing in August 201
