Women's Union () is a section of the Patriotic Union that officially represents the women's wing of the party. It is a grassroots group which provides campaigning, training and support for women within the party, and also general women-specific issues and equal rights.
The group was founded on 22 March 1982 as a result of increasing pressure to introduce women's suffrage to Liechtenstein. The Patriotic Union first supported its introduction in 1972, but a referendum on the topic was rejected by male-only voters in 1973. Following a successful referendum (among men only) in July 1984, women's suffrage was introduced to Liechtenstein.
