Grechetto or Grechetto bianco is a white Italian wine grape variety of Greek origins. The grape is planted throughout central Italy, particularly in the Umbria region where it is used in the Denominazione di origine controllata (DOC) wine Orvieto and Denominazione di origine controllata (DOC) wine Valdichiana Toscana. It is primarily a blending grape, though some varietal wine is also produced. Grechetto is commonly blended with Chardonnay, Malvasia, Trebbiano and Verdello. The grape's thick skin provides good resistance to downy mildew which can attack the grape late in the harvest season. This makes Grechetto a suitable blending grape in the production of Vin Santo.

The thick skin of Grechetto grapes allows the grape to be harvested late with high sugar levels. This works well in the production of dessert wines. There are at least two sub-varieties of Grechetto-Grechetto di Todi and Grechetto Spoletino with the former being more widely planted in the area. The Grechetto vine is low yielding and able to produce concentrated flavours. The grape is primarily used as a blending grape where it adds richness and structure to the wines. It is most often blended with Chardonnay, Trebbiano, Malvasia and Verdello. In Umbria, Grechetto can add herbal and nutty flavours to the wine.
