Lailani (foaled 2 February 1998) is a British Thoroughbred racehorse and broodmare. In a racing career which lasted from October 2000 until October 2001 she won seven of her ten races including Group One/ Grade I races in three countries. After showing little ability in two races as a juvenile she made relentless progress as a three-year-old, winning seven consecutive races including the Irish Oaks in Ireland, the Nassau Stakes in England and the Flower Bowl Invitational Stakes in the United States. After her retirement from racing she had some success as a broodmare.
