The Global Organization of Parliamentarians Against Corruption (GOPAC; Arabic: المنظمة العالمية للبرلمانيين ضد الفساد; French: Organisation mondiale des parlementaires contre la corruption; Spanish: "Organización Mundialde Parlamentarios Contra la Corrupción") is an international nongovernmental organization made up of parliamentarians from across the world, working together to combat corruption, strengthen good government, and uphold the rule of law.

Based in Ottawa, Ontario, Canada, GOPAC has sixty-four national chapters in five continental associations.

GOPAC was founded in October 2002 as a result of a Global Conference in Ottawa, Ontario, Canada which brought together approximately 170 parliamentarians and 400 observers who were part of the international leadership in the fight against political corruption and for good governance.

There are also National Chapters in sixty-four countries, grouped into five continental regions: Africa; Latin America; Oceania; Arab; and Southeast Asia.

Similarly, national chapters can be members of GOPAC even if their continent has not formed a continental association.
