At 679 m above sea level (NHN), the Großer Gleichberg is the higher of the two adjacent mountaintops known as the Gleichberge east of Römhild in the landscape of Grabfeld and the county of Hildburghausen in the German state of Thuringia. It was formed in the Tertiary volcanic field of the Heldburger Gangschar and is the highest point today of that formation.
