As a producer-only market, everything sold at the Columbia Farmers Market is offered by the farmers and artisans who help sustain the culture, economy, and environment of our region. If you did not grow or produce it yourself, you cannot sell it here. This ensures the freshest and highest quality product for our consumers, who can find out exactly where their food came from and how it was grown or raised. The Columbia Farmers Market has almost 80 vendors, most of whom are located in or near Boone County.
