Gallatin County is the fourth-largest county in Montana, spanning 2,517 square miles (World Population Review). Home to the iconic Bridger Mountains, Gallatin Mountains, and Gallatin River, the county is known for its rich natural beauty. It also boasts West Yellowstone’s entrance to Yellowstone National Park, one of the most popular national parks in the United States.

The county seat of Gallatin County is Bozeman, a city often referred to as “the most liveable place” thanks to its small-town feel, despite its population of over 50,000 residents (Visit Montana). Bozeman was founded in 1864, after gold was discovered nearby in the Montana goldfields.

Gallatin County also hosts part of Big Sky Resort, one of the largest and most famous ski resorts in the country. According to the Gallatin County Government, nearly half of the land in the county is publicly owned by the Gallatin National Forest, the State of Montana, the Bureau of Land Management, or the National Park Service.

Humans have inhabited Gallatin County for thousands of years. Native American tribes, including the Shoshone, Nez Perce, Blackfeet, Flathead, and Sioux resided in the area prior to the arrival of European settlers.

On their journey across the United States in the 17th century, the Lewis and Clark Expedition passed through what is now the Gallatin Valley. Meriwether Lewis named the area after the United States Treasury Secretary, Albert Gallatin, who served under President Thomas Jefferson (The Origin of Certain Place Names in the United States).
