Mimi (1888 – 1907) was a dual classic-winning British Thoroughbred racehorse and broodmare. As a two-year-old in 1890 she showed very promising form to win her first four starts but was well beaten when stepped up in class to contest the Middle Park Plate and the Dewhurst Plate. She established herself as the best filly of her generation in May 1891 with three wins in 26 days, taking the 1000 Guineas over one mile, the Newmarket Stakes over ten furlongs and the Oaks Stakes over one and a half miles. She was subsequently beaten in the Prince of Wales Stakes at Leicester and was no match for Common in the St Leger. She was retired from racing at the end of the year and went on to have some success as a dam of winners.
