Quick answer: Wrangell-St. Elias in Alaska is the largest national park in the United States at 13,175,799 acres — more than six times the size of Yellowstone. Death Valley is the largest park in the contiguous 48 states at 3.4 million acres.

Alaska dominates this list. Seven of the ten largest national parks in the United States are in Alaska — a consequence of the Alaska National Interest Lands Conservation Act of 1980, which added more than 47 million acres to the national park system in a single stroke. Wrangell-St. Elias alone is larger than Yellowstone, Yosemite, and the entire country of Switzerland combined.

Lake Clark National Park and Preserve protects 2,619,733 acres of southwest Alaska where the Alaska Range meets the Aleutian Range in the glacier-covered Chigmit Mountains. Two active volcanoes rise over tundra valleys, sockeye salmon crowd five river systems each summer, and brown bears gather on the Cook Inlet coast in concentrations rare anywhere in the world. The park has no road access; the only way in is by small aircraft or, along the southern coast, by boat. About 12,000 visitors arrived in 2023, and Dena'ina Athabascan communities have relied on the land for thousands of years under federally recognized subsistence rights.
