Eugénia Miskolczy Meller (Hungarian: Mellerné Miskolczy Eugénia 14 January 1872 – 1945) was one of the most active feminists and women's rights activists in Hungary from the turn of the century to the interwar period.
One of the founding members of the Feminist Association, she served as a leader for many of the organizations committees and events, arguing for gender equality, as well as women's suffrage.
A pacifist, Meller worked with the Women's International League for Peace and Freedom (WILPF) arguing for disarmament and urging the passage of international laws codifying citizenship regulations to protect women.
Though she had converted to Lutheranism, she was arrested when the Nazis invaded Hungary in 1944 and disappeared.
In 1946, she was posthumously honored for her humanitarian works.
