The Grainger County Tomato Festival was organized in 1992 to promote Grainger County Tomatoes. Our mission is to promote all Grainger County agricultural products, specifically the Grainger County Tomato, and to promote the many local artists and craftsmen we have in our area. Over the years we have added a number of special events making the festival one of the largest free festivals in East Tennessee. The festival is always the last full weekend in July.
