Malheur County is one of the 36 counties in the state of Oregon. In 2020, about 31,571 people lived here. Its main town, called the county seat, is Vale. The biggest city in the county is Ontario.

The county got its name from the Malheur River, which flows through it. The word "malheur" comes from French and means "misfortune" or "tragedy." Malheur County is part of a larger area that includes Ontario and is also connected to the Boise area. It is considered part of Eastern Oregon.

History of Malheur County

Malheur County was officially created on February 17, 1887. It was formed from the southern part of Baker County. The first people to settle here were miners and ranchers in the early 1860s.

A big change happened in 1863 when gold was discovered. This brought more people to the area, leading to new towns and farms. Later, in the 1890s, many Basque people moved to the region. They mostly worked with sheep, raising them for wool and meat.
