Whizgig (1819–1840) was a British Thoroughbred racehorse and broodmare who won the classic 1000 Guineas at Newmarket in 1822. In a racing career which lasted from April 1822 until May 1824 she ran fourteen times and won seven races. Unraced as a two-year-old, Whizgig won six of her seven races in 1822, her only defeat coming in the Oaks Stakes. She remained in training for a further two seasons, but was less successful, winning only one more race. She later became a successful broodmare.
