Elin Sofia Elisabeth "Lilly" Hellström (née Kullberg; 21 August 1866 – 2 March 1930) was a Swedish schoolteacher, children's newspaper editor and an active member of the Swedish suffrage movement. In 1917, she established Moderata Kvinnors Rösträttsförening (Moderate Party's Women's Suffrage Association) under the National Association for Women's Suffrage (LKPR). After the death of her close friend and collaborator Stina Quint, Hellström became more politically active in the conservative Allmänna valmansförbundet.
