|Horse (Equus ferus caballus)|
Plucky Liege (1912-1937) was a British Thoroughbred filly racehorse who was sent to Lower Normandy in France after her racing career ended where she became one of the most important broodmares of the 20th Century. 
Foaled in England, Plucky Liege was bred by Sir Herbert Stern, 1st Baron Michelham. She was sired by Spearmint, a winner of the two most prestigious races in England and France at the time, the 1906 Epsom Derby and the Grand Prix de Paris. Her dam, Concertina, was a daughter of St. Simon who was one of the most successful sires in history. St. Simon was the Leading sire in Great Britain & Ireland nine times, and the Leading broodmare sire in Great Britain & Ireland six times.
Plucky Liege was purchased by Jefferson Davis Cohn for whom she won four of her thirteen career starts. Retired to broodmare duty at Cohn's Haras du Bois-Roussel in Alençon, France, she produced twelve foals of which eleven were winners. According to Thoroughbred Heritage, "nearly every major runner in the world today carries at least one strain of Plucky Liege." In addition to the important offspring of her daughters Marguerite de Valois and Noor Jahan, Plucky Liege produced three very influential sires:
- Sir Gallahad III (b. 1920) - Leading sire in North America (1930, 1933, 1934, 1940), Leading broodmare sire in North America, (1939, 1943-1952, 1955)
- Bull Dog (b. 1927) - Leading sire in North America (1943), Leading broodmare sire in North America (1953, 1954, 1956)
- Bois Roussel (b. 1935) - English Champion Three-Year-Old Colt, won the Epsom Derby. Leading broodmare sire in Great Britain & Ireland in 1959 and 1960. Among others, he was the sire of Tehran and Migoli.
In October of 1933, Jefferson Davis Cohn sold his racing operations, including Plucky Liege, to Leon Volterra. She died in 1937 at age twenty-five.
