The Hainleite is a Muschelkalk ridge of hills up to 463.2 m above sea level (NN) in northern Thuringia, Germany.
It is bordered to the north by the Kyffhäuser Hills (German: Kyffhäuser Gebirge) on the other side of the Wipper, to the east – beyond the so-called Thuringian Gate, a gorge carved out by the Unstrut near little Sachsenburg – by the Schmücke and the Hohe Schrecke, and to the south and southwest by the Thuringian Basin.
The highest elevation[1] is the 463.2 m above sea level (NN) point located in the western part of the Hainleite between Immenrode and Straußberg.
The vegetation on the Hainleite is characterised by mixed woods and, especially in the east, by dense beech forest.
The region north of the Hainleite in the valley of the Wipper between Bad Frankenhausen and Artern is also known as the Diamond Meadow (Diamantene Aue).
