Gail (Slovene: Zilja, Italian: Zeglia) is the name of a river in southern Austria, the largest right tributary of the Drava.

The name Gē'lias is of ancient Illyrian origin, denoting foaming waters. The river is documented as Gila in a 1090 deed. The Slovene name Zilja is also common as the lower Gail Valley is a traditional settlement area of the Carinthian Slovenes and a language region of the distinct Gail Valley dialect.

The river source is located east of the Kartitsch Saddle and the Puster Valley in the Tyrolean municipality of Obertilliach. It flows from west to east through the Southern Limestone Alps, between the Gailtal Alps in the north and the Carnic Alps in the south. The river reaches the state of Carinthia in Lesachtal and from Kötschach-Mauthen runs down the broader Gail Valley (German: Gailtal) with its steep slopes, parallel to the borders with Italy and Slovenia. Beyond its confluence with the Slizza (Gailitz) tributary in Arnoldstein, the Gail joins the Drava River beneath the western Karawanks mountain range near the village of Maria Gail, part of the city of Villach.
