Ma Biche (foaled 1980) was an American-bred, French-trained Thoroughbred racehorse and broodmare who won the classic 1000 Guineas at Newmarket Racecourse in 1983. The filly was the best racehorse of her age and sex in Europe in 1982 when she won two Group One races: the Prix Robert Papin in France and the Cheveley Park Stakes in England.
