Rosa Ward OBE, JP (10 April 1893 – 17 August 1984) was a pioneer of the Girl Guide movement.

It provided 50 teams of volunteer adult Girl Guide leaders to work in close cooperation with the British government and the United Nations Relief and Rehabilitation Administration (UNRRA).

Each team provided on-the-ground support in Europe after World War II, including Bergen-Belsen displaced persons camp.

[11][12] She also oversaw a significant fundraising effort to equip teams and train volunteer leaders,[13] with Girl Guides in the UK and across the Commonwealth raising £168,890 (equivalent to £4,600,000 in 2023)[14] towards GIS's relief work.

[15] Ward first travelled to the British occupation zone in Germany in November 1945,[16] making an annual tour of every GIS team in Europe for the subsequent five years.
