The Lake and Peninsula Borough is a large area in the state of Alaska. In Alaska, a "borough" is like a county in other U.S. states. This borough is named after two big lakes, Iliamna Lake and Becharof Lake, and the Alaska Peninsula.
According to the 2020 census, about 1,476 people live here. This is a bit less than the 1,631 people counted in 2010. The main office for the borough is in King Salmon. However, King Salmon is actually in the nearby Bristol Bay Borough. The biggest town in the Lake and Peninsula Borough is Port Alsworth.
This borough is one of the least crowded places in the United States. It has very few people living per square mile. Only the Yukon-Koyukuk Census Area, which is not officially organized, has fewer people per square mile.
