The Hexastalian Triple Crown of Thoroughbred Racing is a series of three horse races consisting of the Káprázatos Cup, Central Stakes, and Hexastalian Derby. To achieve the crown, one must win all three races. These races are open only to Hexastalian horses of three years of age*, who have either earned a placement through participation in qualifying races or meet the standards of quality and are willing to pay the entry fees. Female horses (fillies) were barred from participation before 2013; despite their participation in the races now, they are still a rare sight. Between the Triple Crown's foundation in 1899 and its 1962 running, the Royal Cup was run as the October leg of the series. It was replaced by the Káprázatos Stakes, subsequently renamed the Káprázatos Cup, in the 1963 edition. In total, ten horses have won all three races of the Triple Crown. Their names and years of achievement are as follows:
•Nagy Császár, 1900
•Horizont, 1922
•Kerekasztal, 1934
•Feketerigó Dala, 1953
•Mogyorófa, 1957
•Rajmond Álma, 1961
•Nagy Gondviselés, 1966
•Star Dancer, 1973
•Cicero Neptunus, 1996
•Tempestuous, 2018
*In thoroughbreds, all horses are treated as if they were born on January 1st of their birth year.
