The Kleiner Gleichberg (641.3 m above sea level (NHN)) is the slightly lower of the two Gleichberge mountains, east of the village of Römhild in the country of Grabfeld in the county of Hildburghausen in the German state of Thuringia. The Celtic Oppidum Steinsburg is located on the mountain. Because of the proximity of its larger brother, the Großer Gleichberg, which is less than 3 kilometres away and, at 679.0 m, slightly higher, the Kleiner Gleichberg is not particularly dominant. Nevertheless, it has a topographic prominence of over 200 metres.
