Twin Falls County is an area in the south central part of Idaho, a state in the United States. In 2020, about 90,046 people lived here. This makes it the fifth-most populated county in Idaho. The main city and biggest city is Twin Falls. Twin Falls County is part of the larger Twin Falls city area.
Before the 1860s, the land that is now Twin Falls County was part of Shoshone lands. Later, it became part of the Oregon Country. In 1864, it was first set up as part of Owyhee County in the Idaho Territory. Then, in 1879, it became part of Cassia County. The county gets its name from a special waterfall on the Snake River. This waterfall is called Twin Falls because it splits into two parts. The Snake River forms the northern edge of the county.
Even after Idaho became a state in 1890, the Twin Falls area had very few people. Not many towns were there. This changed when the city of Twin Falls was started in 1904. Also, the Milner Dam was finished in 1905. Most of the other towns in the county were built around this time. These new communities needed their own local government. They were about 80 miles (129 km) away from Cassia County's main town, Albion. So, the Idaho Legislature created Twin Falls County on February 21, 1907.
