Omegna (Italian: [oˈmeɲɲa], Lombard: [uˈmɛɲa], Piedmontese: [ʊˈmɛɲa]) is a comune (municipality) in the Province of Verbano-Cusio-Ossola in the Italian region Piedmont , located about 100 kilometers (62 mi) northeast of Turin and about 13 kilometers (8 mi) southwest of Verbania at the northernmost point of Lago d’Orta and traversed by the Nigoglia , the lake's sole outflow.

A vibrant street market takes place every Thursday morning along the lakeside boulevard. A daily ferry service links Omegna with the surrounding towns and villages along the lake.

The presence of ancient settlements in the area has been confirmed by excavations conducted in the frazione of Cireggio, with archaeological findings dating back to the late Bronze and Iron Ages. Omegna is first mentioned in 1221 AD, when the population swore allegiance to the commune of Novara .

In the 19th and early 20th centuries, Omegna developed into an industrial center, serving as Italy's primary production hub for pots and small household appliances for many years.
