Aukštaitija (Lithuanian pronunciation: [ɐukʃˈtɐǐːtʲɪjɐ]; literally Highland or Upland) is the name of one of five ethnographic regions of Lithuania.

[2][3] The name comes from the fact that the lands are in the upper basin of the Nemunas, as opposed to the Lowlands that begin from Šiauliai westward.

First of all, you made and announced a decision about the land of Samogitia, which is our inheritance and our homeland from the legal succession of the ancestors and elders.

[8] Some German sources also titled Grand Duke Gediminas, after whom the Gediminids dynasty is named, Rex de Owsteiten (King of Aukštaitija).

Since the 15th century, the Trakai and Vilnius voivodeships made up Aukštaitija, a political and ethnic entity also known as Lithuania proper.
