Preserve (1832–1855) was a British
Thoroughbred racehorse and broodmare who won the
classic 1000 Guineas at
Newmarket Racecourse in 1835. She was the leading British two-year-old filly in 1834, when she was unbeaten in three races at Newmarket. In the following spring she added a victory in the 1000 Guineas before finishing second to
Queen of Trumps when favourite for the
Oaks Stakes a month later. She returned to win three races at
Goodwood Racecourse before ending her career by running fourth in the
St Leger Stakes. After her retirement from racing, Preserve became a successful broodmare, whose direct descendants have won many important races, especially in
North America.
