Sayajirao (1944–1966) was a British Thoroughbred racehorse. A full brother to 1945 Epsom Derby winner, Dante, he was out of the mare Rosy Legend and sired by the great Nearco who is described by Thoroughbred Heritage as "one of the greatest racehorses of the Twentieth Century" and "one of the most important sires of the century."^[1] Nearco was not only unbeaten in racing, but also the patriarch of the most dominant sire line in Thoroughbred history.

Sayajirao was purchased as a yearling by HH Maharaja of Baroda for what at the time was the very substantial sum of 28,000 guineas, the then equivalent of US$117,600.^[2]

Racing at age three, Sayajirao won the Lingfield Derby Trial and the Irish Derby Stakes.^[3] He ran third in both The Derby and the 2,000 Guineas Stakes then won the third leg of the English Triple Crown, the St. Leger Stakes at Doncaster Racecourse.^[4]

Retired to stud in 1949, Sayajirao sired the winners of 410 races. His daughters foaled the winners of 261 races. Among those he sired were:

• Dark Issue (b. 1952) - won the Irish 1,000 Guineas
