The International Telecommunications Satellite Organization (ITSO) is an intergovernmental organization charged with overseeing the public service obligations of Intelsat, which was privatized in 2001.

The landmark headquarters of this organization was located in Washington D.C., United States.

States join ITSO by ratifying a multilateral treaty known as the Agreement relating to the International Telecommunications Satellite Organization.

Bulgaria ratified the treaty in 1996 but denounced it and withdrew from the organization in 2012.
