Annie Kenney (13 September 1879 – 9 July 1953) was an English working class suffragette who became a leading figure in the Women's Social and Political Union. She attracted the attention of the press and the public in 1905, when she, and Christabel Pankhurst, were imprisoned for several days for assault and obstruction, after heckling Sir Edward Grey at a Liberal rally in Manchester on the issue of votes for women. This incident is credited with inaugurating a new phase in the struggle for women's suffrage in the UK, with the adoption of militant tactics.
