Lyde Browne FSA (died 10 September 1787, Foster Lane, Cheapside, London) was an 18th-century English antiquary and banker, who owned one of the largest antiquities collections of the time. This now forms the nucleus of the classical sculpture collections of the Hermitage Museum in Saint Petersburg and the Pavlovsk Palace in the city's suburbs. The Hermitage Museum website calls him John Lyde-Brown, as does The Oxford Encyclopedia of Ancient Greece and Rome.
