The Karaš (in Serbian, also Cyrillic: Караш) or Caraș (in Romanian) is a 110-kilometre (68 mi) long river in the Banat region of Vojvodina, Serbia and Romania and a left tributary of the Danube.

[1][2] The Karaš drains an area of 1,400 square kilometres (540 sq mi) and although it has been channeled it is not navigable.

It runs through Romania for 50 kilometres (31 mi), flowing to the north in its early reaches before turning southwest at the town of Carașova where it receives many short tributaries, most notably, the left tributary of the Lișava, then passes many villages (including Giurgiova, Ticvaniu Mare, Grădinari, Vărădia, Mercina, Vrani) before it enters the Serbian province of Vojvodina.

[2] Right after crossing the border, the Karaš receives its two major tributaries, the Borugu from the right, and the Vicinic from the left.
