Tortum (Georgian: თორთომი or თორთუმი, romanized: tortomi or tortumi; Ottoman Turkish: تورتوم; Armenian: Թորթում, romanized: Tortum) is a municipality and district of Erzurum Province, Turkey.

[1] The current mayor is Muammer Yiğider from the Justice and Development Party (AKP).

[4] Tortum was part of the area known as Diaueni or Tao and was ruled by Diauehi, Urartians, Iberians, Armenians, Georgians, Romans, Persians and Byzantines.

The region was in the early Ottoman period largely Christian but acquired a Muslim majority in the mid 18th century, as the Georgian population fled to the inner provinces of Georgia.

[5] During World War I, Ottoman troops crossed Tortum in the disastrous Battle of Sarikamish.
