Edith Mansell-Moullin was an English suffragist of Welsh heritage and social activist. Proud of her Welsh roots, she founded the Cymric Suffrage Union, which was dedicated to gaining women's suffrage for Welsh women. She was the co-organizer of the Welsh contingent of the 1911 procession of the Women’s Suffrage Union’s "Great Demonstration" held in 1911 in London. Part of the more militant British suffrage contingent, she was imprisoned for dissidence and refused to stop government agitation during World War I.

Women's suffrage in Wales has historically been marginalised due to the prominence of societies and political groups in England which led the reform for women throughout the United Kingdom. Due to differing social structures and a heavily industrialised working-class society, the growth of a national movement in Wales grew but then stuttered in the late nineteenth century in comparison with that of England. Nevertheless, distinct Welsh groups and individuals rose to prominence and were vocal in the rise of suffrage in Wales and the rest of Great Britain.
