Muscat Blanc à Petits Grains is a white wine grape that is a member of the Muscat family of Vitis vinifera. Its name comes from its characteristic small berry size and tight clusters. It is known under a variety of local names such as Muscat Blanc, Muscat Canelli, Moscato Bianco, Muscat de Frontignan, Muscat de Lunel, Muscat d'Alsace, Muskateller, Moscatel de Grano Menudo, Moscatel Rosé and Sárgamuskotály .

While technically a white grape, there are strains of Muscat Blanc à Petits Grains vines that produce berries that are pink or reddish brown. The same vine could potentially produce berries of one color one year and a different color the next. These strains are more prevalent in Australia, where the grape is also known as Frontignac and Brown Muscat. South Africa's Muskadel strain tends to show the same darker characteristics. Variants where the differing grape colour is stable are typically classified as separate grape varieties Muscat Rouge à Petit Grains for red skin colour and Muscat Rose à Petit Grains for pink skin colour.
