Trophonius (foaled 1808) was a British Thoroughbred racehorse and sire and best known for winning the classic 2000 Guineas in 1811. Trophonius won his first three races at Newmarket Racecourse in the spring of 1811, including the Guineas and the Newmarket Stakes on the following afternoon, but ran disappointingly when favourite for the Epsom Derby. He never recovered his best form and was beaten in his remaining seven races. Shortly after his retirement he was sold and exported to stand as a breeding stallion in Russia.

Trophonius was a black horse bred by Mr Kellermann. He was sired by Sorcerer, a successful racehorse and three-time Champion sire in Britain. Amongst Sorcerer's other progeny were 2000 Guineas and Derby winner Smolensko, St. Leger winner Soothsayer and the Oaks winners Morel, Maid of Orleans and Sorcery. Trophonius was the second of only three foals produced by his dam, an unnamed daughter of Dungannon bred by Dennis O'Kelly.

Trophonius's racing career overlapped with that of a horse of the same name owned by the Earl of Darlington: the Guineas winner was sometimes known as Black Trophonius to distinguish him from his bay namesake. He was owned throughout his racing career by Robert Andrew.
