Ravalli County is a county in the southwestern part of the U.S. state of Montana. As of the 2010 census, the population was 40,212. Its county seat is Hamilton.
Ravalli County is part of a north/south mountain valley bordered by the Sapphire Mountains on the East and the Bitterroot Mountains on the West. It is often referred to as the Bitterroot Valley, which is named for the Bitterroot Flower. The county is on the Pacific Ocean side of the Continental Divide, which follows the Idaho-Montana border from Wyoming until Ravalli County. Here, it turns east into Montana, between Chief Joseph Pass and Lost Trail Pass, and follows the Ravalli County-Beaverhead County border.
Ravalli County was once home to the Bitterroot Salish tribe. The tribe was first encountered in 1805 by the Lewis and Clark Expedition, which noted their friendly nature. The Catholic Church took an interest in creating a mission in the area, and in 1841, Stevensville was founded. In 1891, the Salish tribe moved to the current Flathead Reservation under the Treaty of Hellgate.
