Lillian Gertrude Browse (21 April 1906 – 2 December 2005) was a London-based art dealer and art historian, and was a partner in two London galleries, first Roland, Browse and Delbanco and then Browse & Darby.
During the Second World War she organised exhibitions at the National Gallery, whose collections had been removed to the country for safety.
She wrote a number of monographs on 20th-century artists, including important works on Walter Sickert and Sir William Nicholson.
She was nicknamed "The Duchess of Cork Street", and used that name as the title of her autobiography.
