Welcome to the 118th Annual Rosebud-Treasure County Fair!

Mark your calendars for Wednesday, July 15 through Saturday, July 18, 2026, and join us for Rosebud County’s biggest annual celebration. Whether you’re an exhibitor, a participant, or simply coming to enjoy the festivities, the Fair Board invites everyone to take part in this long-standing community tradition.

Step inside our air-conditioned Exhibit Hall, open daily from 10:00 a.m. to 7:00 p.m., to explore a wide variety of displays—from 4-H and FFA projects to consumer education exhibits and creative entries from local residents. Don’t forget to stroll through the outdoor exhibits for even more to see and experience.

While you’re here, grab a bite from one of the many food vendors, enjoy live performances on the Free Stage, and take a spin at the Mighty Thomas Carnival, both located on the lively grass midway.

Come celebrate community, creativity, and tradition at the 118th Rosebud-Treasure County Fair!
