Riverqueen
Riverqueen (1973 – after 1989) was a French Thoroughbred racehorse and broodmare. After winning her only race as a two-year-old she emerged as one of the best fillies in Europe in the spring and summer of 1976, winning the Prix de la Grotte, Poule d'Essai des Pouliches and Prix Saint-Alary. After her winning run was brought to an end by Pawneese in the Prix de Diane she rebounded to become the first three-year-old filly to win the weight-for-age Grand Prix de Saint-Cloud. After running poorly in her last two races she was retired from racing and had some success as a broodmare. Her last recorded foal was born in 1989.
