Vitovska or Vitouska, also known in Slovenian as Vitovska Grganja or Garganja is an Italian and Slovene wine grape predominantly planted in the Friuli-Venezia Giulia region and in the Kras in the Slovenian Littoral. The name of the grape is of Slovenian origin, but is now mostly found in the lower Isonzo and Carso regions of northeast Italy. The grape produces a dry white wine.

Vitovska is a cross between Prosecco Tondo and Malvasia Bianca Lunga.
