Wassl (27 April 1980 – after 1998) was a British Thoroughbred racehorse and sire. As a two-year-old he showed great promise when winning on his debut but missed the rest of the season through injury. In the following spring he won the Greenham Stakes and then rebounded from a poor run in the 2000 Guineas to win the Irish 2,000 Guineas. He failed to win again in 1983 but was placed in the Sussex Stakes, Prix du Moulin and Joe McGrath Memorial Stakes. He dead-heated for first place in the Lockinge Stakes on his first run of 1984 but was well beaten in his four other races as a four-year-old. After his retirement from racing he stood as a breeding stallion in Ireland and Japan and had limited success as a sire of winners.
