Seattle Dancer (April 22, 1984 – June 2, 2007) was an Irish Thoroughbred racehorse who in 1985 became the world's most expensive yearling ever sold at public auction.
[3][1] Seattle Dancer's new owners were Stavros Niarchos (Greece), Susan Magnier and her father, Vincent O'Brien (Ireland), Robert Sangster (England), and a California businessman, Daniel Schwartz.
The colt was sent to Ballydoyle in Ireland, but a virus swept through the stables that kept a weakened Seattle Dancer out of racing as a two-year-old.
In his next start, at Longchamp Racecourse in Paris, France, he finished sixth in the Group 1 Prix du Jockey Club.
[5] At the same racecourse, in what would prove to be his final race, Seattle Dancer ran second in the Group 1 Grand Prix de Paris.
