Into which body of water does the Yukon River discharge?

The Yukon River discharges into the Bering Sea. Its mouth lies in western Alaska, where the river spreads through the broad Yukon–Kuskokwim Delta before reaching the sea.

The Yukon is one of North America's major rivers, flowing roughly 3,190 kilometres from its headwaters near Atlin Lake in British Columbia through Canada's Yukon territory and across Alaska. The river's name is also preserved in the name of the Canadian territory it crosses. Much of the river's lower course is in Alaska, where it becomes a vast, slow-moving system of distributaries and wetlands.

A common mix-up is to name the Yukon–Kuskokwim Delta as the answer. That is the geographic region where the Yukon and Kuskokwim systems empty, but the body of water receiving the Yukon is the Bering Sea. The river is also sometimes confused with the Gulf of Alaska, which is farther south and is not the Yukon River's outlet. The delta supports exceptionally rich wetland and wildlife habitats and has long been important to Indigenous communities and river transportation.
