Elma Danielsson née Sundquist (1 March 1865, Falun - 8 February 1936, Lomma), was a Swedish journalist and politician (Social Democrat).

She worked as a teacher in the public school system and moved to Malmö with her fiancée Axel Danielsson, with whom she had an on and off relationship from their engagement in 1881 onward - they married sixteen years later, in 1897.

When Axel was imprisoned for blasphemy in 1889, she managed the paper until his release in 1890.

August Strindberg reportedly once remarked to Danielsson that he was lucky to have "a fiancee with a spark".

[2] Danielsson was a driving spokesperson of women's rights within the Swedish working-class movement: she was the founder of the Kvinnliga arbetarklubben (Women's Worker's Association) in 1888, the first socialist organisation for women workers in Sweden, and served as its chairperson in 1888–90.
