Rut (pronounced [ˈɾuːt]; formerly Nemški Rut[3] or Nemška Koritnica,[4] German: Deutschruth;[3][5] Italian: Rutte di Gracova[6]) is a village north of Koritnica in the Municipality of Tolmin in the Littoral region of Slovenia.

[7] Rut was attested in historical sources as Corithnich Reutharius in 1310, Cordnitze super Tulminum in 1480, Krytha bey der Pfarr in 1515, Coriniza di Baza in 1566, and Teutsch Coritniza in 1624, among many other names.

[8] It was labeled D. Ober Koritniza oder Deutsch Greuth in the late-18th-century Josephinian Land Survey.

[12] The Slovene name of the village was changed from Nemški Rut to Rut after the Second World War[8] as part of efforts by Slovenia's postwar communist government to remove German elements from toponyms.

[13] The parish church in the settlement is dedicated to Saint Lambert and belongs to the Koper Diocese.
