Niobrara County

Niobrara County is an administrative division in eastern Wyoming with rolling grasslands and the Thunder Basin National Grassland at its core. The area consists mainly of open prairie with a small population concentrated in towns like Lusk, the county seat.

The county was established in 1911 from territory that previously belonged to Converse County. Its name comes from the Niobrara River, which flows near Lusk and runs through the region.

People here maintain strong ties to German, English, and Irish heritage from early settlers who shaped the region. These roots show up in local family names, community traditions, and how neighbors connect with one another.

Government offices operate in Lusk, the county seat, with services available on weekdays. Planning a visit during warmer months is wise, as winters can be harsh and winds are common year-round.

With fewer than 2,500 residents, this is one of the least populated counties in Wyoming. The small population creates a sense of wide-open space and solitude in this high plains landscape.
