Stalker (9 March 1983 – after 2002) was a British Thoroughbred racehorse and sire. After failing to sell as a yearling he became a very successful racehorse as a two-year-old in 1985. He won four of his eight races that year including the Gimcrack Stakes and the Middle Park Stakes and was also placed in the Richmond Stakes and the Mill Reef Stakes. He failed to show any worthwhile form as a three-year-old and was retired from racing. He stood as a breeding stallion in Ireland and Cyprus with limited success.
