Agda Georgina Dorothea Alexandra Montelius née Reuterskiöld (23 April 1850 – 27 October 1920) was a Swedish philanthropist and feminist.

She was a leading figure of the Swedish philanthropy, active for the struggle of women's suffrage, and chairwoman of the Fredrika Bremer Association in 1903–1920.

[1] Montelius was born in Köping in 1850, the daughter of the government defence minister and noble Lieutenant General Alexander Reuterskiöld and Anna Schenström.

In 1886, Montelius officially became a member of the women's rights organisation of Sophie Adlersparre: the Fredrika Bremer Association or FBF.

In 1899, a delegation from the FBF presented a suggestion of women's suffrage to Prime Minister Erik Gustaf Boström.

In 1902, the Swedish National Association for Women's Suffrage (Landsföreningen för kvinnans politiska rösträtt, LKPR) was founded.

However, on 18 February, Montelius was called to meet with Queen Victoria of Baden, who demanded a stop of "The foolish presumption of women" to involve in politics.

The king referred the matter to Knut Wallenberg, Minister for Foreign Affairs, who warned them that such an action could damage Swedish neutrality.
