Edith Ballantyne (born 10 December 1922) is a Czech-born Canadian citizen, who has been a prominent member of the Women's International League for Peace and Freedom (WILPF) since 1969.

Unable to speak English, she was taught the language by Women's International League for Peace and Freedom (WILPF) volunteers, who kept track of the Bohemian refugees and tried to assist them in making adjustments to life in Canada.

Joining the WILPF, Müller found their message of pacifism and human rights inspiring but lost touch with the group when she moved to Montreal in 1945.

The following year, she became the Secretary General of the organisation,[1][2] and accepted a full-time position to work on improving WILPF's interaction with NGOs and the United Nations (UN).

[5] The debates that followed the meeting, resulted in a resolution that idealistic pursuit of pacifism could not replace the recognition that the ultimate goal of peace was to allow people to attain their liberation and live freely.

[11][13] When the World Conference on Women, 1980 was held in Copenhagen, Ballantyne served as chair of program development for NGO Forum, ensuring that there was strong emphasis on peace and disarmament in the discussions of the various workshops.

Coupled with US military involvement in the Contra War, Ballantyne chaired the "International Conference on Nicaragua and Peace in Central America" with Adolfo Pérez Esquivel in Lisbon in 1984 to discuss the escalating arms race.
