Danedream (foaled 7 May 2008) is a German Thoroughbred racehorse best known for winning the 2011 Prix de l'Arc de Triomphe in race record time. She is one of only two German trained horses to win the Arc, the other being Star Appeal in 1975. In November 2011 she became the first German-trained horse to win a Cartier Racing Award.
Danedream won only one of her first seven races before gaining her first important win in the Oaks d'Italia. In the second half of 2011, she showed dramatic improvement, winning the Grosser Preis von Berlin by five lengths and the Grosser Preis von Baden by six before easily beating an international field by five lengths in the Arc. In 2012, Danedream ran poorly in the Grand Prix de Saint-Cloud but then became the first German-trained horse to win the King George VI and Queen Elizabeth Stakes, beating an international field at Ascot.
