Arneis is a white Italian grape varietal originating from Piemonte, Italy. It is most commonly found in the hills of the Roero, northwest of Alba. Arneis (literally "little rascal" in Piemontese) is so called because it is regarded as a somewhat difficult varietal to grow.

For centuries, the white Arneis grape was used to soften the tannins and harshness of Nebbiolo grapes, though today the grape is more commonly seen as a varietal wine. Arneis wines fermented and/or aged in oak will be more full-bodied, while unoaked Arneis can have more aromatics and perfume with aromas of almonds, apricots, peaches and pears.

Arneis pairs well with medium-bodied savory dishes such as pasta with cheese, vinaigrettes with oil-to-vinegar ratios of more than 2:1 ratio, fish, shellfish, and chicken, veal and pork with creamy or buttery sauces.

Cheeses that go well with Arneis include Brie, Camembert, Colby, Crottin, Fontina, Manchego, Monterey Jack, Mozzarella, Provolone, Triple Creme, St. Andre and Zamarano (Spanish sheep-milk cheese).
