Lake Orta (Italian: Lago d'Orta; Lombard and Piedmontese: Lagh d'Òrta) or Cusio (Lombard and Piedmontese: Cusi; Latin: Lacus Cusius) is a lake in northern Italy, west of Lake Maggiore.

Until the 16th century it was called Lago di San Giulio, after Saint Julius of Novara (4th century), the patron saint of the region.
