Lady Cynthia Blanche Mosley (23 August 1898 – 16 May 1933), nicknamed "Cimmie", was a British politician of Anglo-American parentage and the first wife of the British Fascist and New Party politician Sir Oswald Mosley, who was formerly a Member of Parliament in both the Conservative and Labour parties.

Born Cynthia Blanche Curzon at Kedleston Hall, she was the second daughter of Hon. George Curzon (later Marquess Curzon of Kedleston) and his first wife, Mary Victoria Leiter, an American department-store heiress. As the daughter of a Marquess, she was styled Lady Cynthia.

On 11 May 1920, Cynthia married the then-Conservative politician, Oswald Mosley. He was her first and only lover.

They had three children:

After both joined the Labour Party in 1924, she was elected Labour Member of Parliament (MP) for Stoke-on-Trent in 1929, her husband having been elected MP for Smethwick in 1926. Frustrated with the ruling Labour Party's complacent and conservative response to high levels of unemployment, Oswald Mosley formed the New Party on 1 March 1931 which his wife also joined. The party failed to win any seats at the 1931 general election. After that Mosley started his move towards fascist policies, losing many of those who had joined the New Party as a result.
