Finian's Rainbow was foaled on 29 May 2003. A bay gelding, he was bred by J. O'Keeffe. He was sired by Tiraaz, who won the Prix Royal-Oak in 1998. Finian's Rainbow's dam was Trinity Gale, a daughter of top National Hunt sire Strong Gale, who was the leading jump racing sire in Great Britain and Ireland for six seasons. Trinity Gale raced in seven hurdle races in 1993 and 1994, without winning; she did however win a point-to-point race at Ballon Racecourse. Finian's Rainbow died on 24 March 2021 from complications due to colic.
