Maud Alice Burke (3 August 1872 – 10 July 1948), later Lady Cunard, known as Emerald, was an American-born, London-based society hostess.
She had long relationships with the novelist George Moore and the conductor Thomas Beecham, and was the muse of the former and a champion of and fund-raiser for the latter.
She was a supporter of Wallis Simpson during the British abdication crisis of 1936, vainly hoping for a court appointment.
The Second World War ended her era of private patronage and lavish hospitality.
