Oneida County, Idaho

Oneida County is tucked into southeastern Idaho, right along the Utah border. You can see mountains in just about every direction. Malad City serves as the county seat, and this is one of the more rural corners of Idaho.

Farming and ranching are the backbone of the local economy. You’ll find plenty of alfalfa fields, cattle, and wide-open farmland. The Malad River runs through the county and, although it’s not a huge river, it plays an important role in irrigation.

Early Mormon settlers gave the county the name “Oneida,” inspired by the Oneida people of New York. The area also has strong Welsh connections, particularly around Malad City. Oneida County may be quiet and rural, but its mix of mountains, farmland, and Welsh heritage gives it plenty of character.
