The International Federation of Gynaecology and Obstetrics, usually just FIGO ("fee'go") as the acronym of its French name Fédération Internationale de Gynécologie et d'Obstétrique, is a worldwide non-governmental organisation representing obstetricians and gynaecologists in over one hundred territories.

It was founded on 26 July 1954 in Geneva, Switzerland, to "promote the well-being of women and to raise the standard of practice in obstetrics and gynaecology".
