Coeur d'Alene ( (listen) KOR də-LAYN; French: Cœur d'Alène, lit. 'Heart of an Awl' [kœʁ d‿a.lɛn]) is the county seat of Kootenai County, Idaho, United States. It is the largest city in North Idaho and the principal city of the Coeur d'Alene Metropolitan Statistical Area. In 2019, the United States Census Bureau estimated the city's population at 52,414. Couer d'Alene is a satellite city of Spokane, which is located about thirty miles (50 km) to the west in the state of Washington. The two cities are the key components of the Spokane–Coeur d'Alene combined statistical area, of which Coeur d'Alene is the third-largest city (after Spokane and its largest suburb, Spokane Valley). The city is situated on the north shore of the 25-mile (40 km) long Lake Coeur d'Alene and to the west of the Coeur d'Alene Mountains. Locally, Coeur d'Alene is known as the "Lake City," or simply called by its initials, "CDA."
The city is named after the Coeur d'Alene people, a federally recognized tribe of Native Americans who lived along the rivers and lakes of the region, in a territory of 4,000,000 acres (16,000 km2) from eastern Washington to Montana. The native peoples were hunter-gatherers who located their villages and camps near food gathering or processing sites and followed the seasonal cycles, practicing subsistence hunting, fishing, and foraging.
The city began as a fort town; General William Tecumseh Sherman sited what became known as Fort Sherman on the north shore of Lake Coeur d'Alene in 1878. Peopling of the town came when miners and prospectors came to the region after gold and silver deposits were found in what would become the Silver Valley and after the Northern Pacific Railroad reached the town in 1883.
