Mildred Ella Mansel (née Guest, c. 1868 – 11 March 1942) was a British suffragette and organiser for the Women’s Social and Political Union (WSPU) in Bath.

[3] During the Bill of Rights March on 29 June 1909, Mansel was arrested with Evelina Haverfield and Emmeline Pankhurst as they had tried to break into the House of Commons and present a petition to Herbert Asquith, the Prime Minister.

[6] When Grace Roe was sent to Ipswich to recruit for the WSPU and set up a branch, she invited Mansel and Marie Brackenbury to support her there.

[8] She planted an Ilex Aquifolium Fructu-Luteo Holly and the surviving plaque is held in the collection of the Roman Baths Museum.

[12] Mansel was put in charge of coordinating the movement of women between safe houses from 1913, to shelter them after being released from prison under the "Cat and Mouse Act."

[14] When Emmeline Pankhurst died on 14 June 1928, Mansel was one of her pallbearers, alongside other former suffragettes Georgiana Brackenbury, Marie Brackenbury, Marion Wallace Dunlop, Harriet Kerr, Kitty Marshall, Rosamund Massy, Marie Naylor, Ada Wright and Barbara Wylie.
