Terrano or Teran (in Slovene) is primarily a Slovenian and also a Croatian and Italian wine variety, bearing the mark of recognized traditional denomination. It is a member of the Refosco family of grape varieties, which also includes Refosco dal Peduncolo Rosso. Since 2006 it is a wine with a protected designation of origin (PDO) within European Union under the protected designation "Teran".

Traditional Kraški teran does not age well—notably, chemical analyses have confirmed that the content of bivalent iron starts to diminish radically two years after fermentation—and should be consumed within its first year; after that, the wine quickly loses its attractive vitality and can even become bitter and flat.

Terrano wine is primarily grown on the Karst Plateau within the Slovene Littoral wine region (where it is called Kraški teran) and Italian Carso DOC (with two main varieties called Terrano del Carso and Carso Rosso (red Carso)). Teran is the principal red wine grape in these regions. In the Carso DOC, the grape is sometimes blended with Piccola nera. In Italy it is also used in the DOC Cagnina di Romagna in Emilia-Romagna.

The Italian and Slovene parts of the Karst Plateau (Carso and Kras, respectively) are located on either side of the Italian-Slovene border. In this area the Terra Rossa is present in part of the municipalities of Sežana, Komen and Kostanjevica, around the villages of Tomaj and Dutovlje. In Italy, it is present in the area of Monrupino, Sgonico, Duino-Aurisina and in a very limited part of the municipality of Trieste (between Opicina and the Slovenian border). In Croatia, it is found in Western Istria.
