Mon Tresor (8 May 1986 – after 2001) was a British Thoroughbred racehorse and sire. He showed by far his best form as a two-year-old in 1988. After winning two minor races in summer he reached his peak in autumn, winning the Moet & Chandon Rennen in Germany and then recording his biggest win in the Middle Park Stakes. In the following year he finished third in the European Free Handicap on his debut, but his form deteriorated thereafter. He was retired from racing at the end of the year and stood as a breeding stallion with limited success.
