Julia Frances Solly (née Muspratt; 21 December 1862 – 1953) was a British suffragist, feminist and temperance activist. After her marriage, she moved to South Africa, where she became one of the most recognisable feminists in the Cape Colony. Advocating for suffrage, she co-founded the Cape Branch of the Women's Enfranchisement League (WEL), the first organisation in South Africa created to push for women's right to vote. Active as a pacifist, she was against both the Second Boer War and World War I, but believed that the Nazis must be stopped at all cost. She was also active in many social reform programs and was part of the purity movement. For her work on the National Council of Women, she was awarded the King George Silver Jubilee Medal in 1935.
