The International Development Law Organization (IDLO) is an intergovernmental organization dedicated to the promotion of the rule of law.

With a joint focus on the promotion of the rule of law and development, it works to empower people and communities to claim their rights and provides governments with the know-how to realize them. It supports emerging economies and middle-income countries to strengthen their legal capacity and rule of law framework for sustainable development and economic opportunity. It is the only intergovernmental organization with an exclusive mandate to promote the rule of law and has experience working in dozens of countries around the world.

IDLO is headquartered in Rome, Italy has a branch office in The Hague, and is one of many entities that are United Nations General Assembly observers.
