Iliamna Lake or Lake Iliamna (/ˌɪliˈæmnə/ IL-ee-AM-nə; Yup'ik: Nanvarpak; Dena'ina Athabascan: Nila Vena) is a lake in southwest Alaska, at the north end of the Alaska Peninsula, between Kvichak Bay and Cook Inlet, about 100 miles (160 km) west of Seldovia, Alaska. It shares a name with the Iliamna River, which flows into it, and the nearby community of Iliamna, Alaska.

It is the largest lake in Alaska, 7th largest lake in the United States, and twenty-fourth in North America. Covering about 2,600 km2 (1,000 sq mi), Iliamna Lake is 77 miles (124 km) long and up to 22 miles (35 km) wide, with a maximum depth of 988 feet (301 m). Through the Kvichak River, its waters drain into Bristol Bay.
