Lochsong (26 April 1988 – 27 May 2014) was a bay Thoroughbred filly who twice won the Cartier Award as Top European Sprinter and was voted 1993 European Horse of the Year.

Lochsong was a bay mare bred by her owner, Jeff Smith's Littleton stud.

As a two and three-year-old in racing, Lochsong accomplished little until Ian Balding took over as her trainer. In 1992 the filly won the rare Sprint-Handicap triple of Stewards' Cup, Portland Handicap and Ayr Gold Cup. The filly won numerous other top races including the Group 1 Nunthorpe Stakes as well as twice capturing the Group 1 Prix de l'Abbaye at Longchamp in Paris, France.

In addition to her two Top Sprinter awards, Lochsong's performance in the 1993 season won her the most prestigious honor in European horse racing, the Cartier Racing Award as European Horse of the Year.

Lochsong was retired to her owner's Littleton Stud in the parish of Littleton & Harestock in Hampshire, England. On 27 May 2014, Lochsong was euthanised at Littleton after contracting colic.^[1]
