Salix euxina, the eastern crack-willow,[2] is a species of flowering plant in the willow family Salicaceae, native from Turkey to the Caucasus.

The olive green branchlets are hairless (glabrous) and very brittle at the base, so that branches easily break off.

[3][4] The epithet euxina refers to the distribution of the species around the Black Sea, known as Πόντος Εὔξεινος (Pontos Euxeinos) in Ancient Greek.

[4] Salix euxina is native to a narrow region around the east of the Black Sea, including northern Turkey, the North Caucasus and the Transcaucasus, where it is found beside mountain streams.

[1][4] It has been introduced into parts of Europe (Belgium, European Russia, Great Britain and the Netherlands) and Canada (Ontario and Quebec).
