The International Pacific Halibut Commission (IPHC), originally called the International Fisheries Commission, was established in 1923 by a Convention between the governments of Canada and the United States of America. Its mandate is research on and management of the stocks of Pacific halibut (Hippoglossus stenolepis) within the Convention waters of both nations. The IPHC consists of three government-appointed commissioners for each country who serve their terms at the pleasure of the President of the United States and the Canadian government respectively.

The IPHC, an International Fisheries Organization, receives monies from both the U.S. and Canadian governments to support a Director and staff. Annually, the IPHC meets to conduct the business of the Commission. At this annual meeting the budgets, research plans, biomass estimates, catch recommendations, as well as regulatory proposals are discussed and approved then forwarded to the respective governments for implementation. The IPHC staff and offices are currently located in Seattle, Washington.
