The Great Northern Fair is an annual community and agricultural celebration held in Havre, Montana. It is recognised as one of the major fair events on Montana’s Hi-Line and brings together families, farmers, ranchers, local organisations and visitors for several days of entertainment and traditional fair activities.

The five-day event showcases northern Montana’s agricultural heritage, livestock industry and community spirit. Visitors can enjoy rodeo performances, youth rodeo competitions, 4-H livestock exhibitions and auctions, carnival rides, live entertainment and special evening shows.

One of the popular attractions is the demolition derby, which offers exciting motorsport entertainment for spectators. The fairgrounds also provide facilities for agricultural displays, commercial exhibitors, food vendors and family activities.

The event provides opportunities for young agricultural participants to display their livestock projects and demonstrate their skills, while visitors can experience traditional Montana fair entertainment.

The 2027 Great Northern Fair is scheduled for July 14–18 at the Great Northern Fairgrounds in Havre.
