La Grande Rivière Airport (IATA: YGL, ICAO: CYGL) is a regional airport located in the Jamésie territory of northern Quebec, Canada, serving the community of La Grande Rivière and the surrounding James Bay hydroelectric complex. The airport plays a critical role in providing air access to a region that is largely inaccessible by road for much of the year. The airport supports workers, residents, and supplies destined for Hydro-Québec's massive La Grande Complex, one of the largest hydroelectric systems in the world. Air transport is effectively the primary means of reliable passenger travel in this remote subarctic environment. Flights connect La Grande Rivière primarily to Montreal and other northern Quebec communities, with Air Inuit and Air Creebec being key regional carriers serving the area.
