The United Nations Entity for Gender Equality and the Empowerment of Women, also known as UN Women, is a United Nations entity charged with working for gender equality and the empowerment of women. UN Women is charged with advocating for the rights of women and girls, and focusing on a number of issues, including violence against women and violence against LGBT people.

The United Nations Development Fund for Women was established in December 1976 originally as the Voluntary Fund for the United Nations Decade for Women in the International Women's Year. Its first director was Margaret C. Snyder. UNIFEM provided financial and technical assistance to innovative programmes and strategies that promoted women's human rights, political participation and economic security. Since 1976 it supported women's empowerment and gender equality through its programme offices and links with women's organizations in the major regions of the world. Its work on gender responsive budgets began in 1996 in Southern Africa and expanded to include East Africa, Southeast Asia, South Asia, Central America and the Andean region. It worked to increase awareness throughout the UN system of gender responsive budgets as a tool to strengthen economic governance in all countries. In 2011, UNIFEM merged with some other smaller entities to become UN Women.
