Mascarello Giuseppe e Figlio is a prestigious Barolo producer in Piemonte, northwest Italy. The company has been closely associated with the Monprivato vineyard, one of the so-called Barolo crus, since the 1920s, and the single vineyard Monprivato Barolo has become Giuseppe Mascarello's flagship wine since the 1920s.

The eponymous Giuseppe Mascarello tended vineyards in the Langhe before buying his own in 1881. In 1904, his son purchased a part of the Monprivato vineyard and began to make wines there. Fourth-generation Mauro Mascarello took over the running of the estate in 1967, and began making a single-vineyard Monprivato wine in 1970. The famous six-hectare (15-acre) cru became a monopole of Giuseppe Mascarello in 1990.

The Monprivato vineyard's south-westerly aspect and limestone-rich soils has made it one of Barolo's most coveted properties, considered ideal for the Nebbiolo grape variety. In the 1980s, a clone of Nebbiolo called Michét was planted in a small part of the vineyard as an experiment which became the estate's highly regarded Monprivato Cà d'Morisso cuvee. This, alongside the regular Monprivato, is only made in outstanding vintages. The estate prefers traditional winemaking methods, with long fermentations and wines aged in large Slavonian oak casks known as botti. There is little intervention in the vineyard and grapes are harvested by hand.

Giuseppe Mascarello makes several other single-vineyard Barolos, including those from the Santo Stefano di Perno and Villero vineyards. The estate also makes several single-vineyard Barbera d'Alba wines, and a Dolcetto d'Alba.
