Lady Constance Georgina Bulwer-Lytton (12 February 1869 – 2 May 1923), usually known as Constance Lytton, was an influential British suffragette activist, writer, speaker and campaigner for prison reform, votes for women, and birth control. She sometimes used the name Jane Warton. Although born and raised in the privileged ruling class of British society, Lytton rejected this background to join the Women's Social and Political Union (WSPU), the most militant group of suffragette activists campaigning for "Votes for Women".
