Marietta Gazzaniga (1824 – 2 January 1884) was an Italian operatic soprano.
Gazzaniga was born in Voghera and studied singing with Alberto Mazzucato in Milan. Her debut season was in 1840 in Voghera where she sang Jane Seymour in Donizetti's Anna Bolena and Romeo in Bellini's I Capuleti e i Montecchi.
She sang the title role in the premiere of Verdi's Luisa Miller at the Teatro di San Carlo in Naples in 1849, and a year later she sang Lina in the premiere of Verdi's Stiffelio in Trieste. Starting in 1851 she began singing at La Scala. In 1852 she sang Gilda in Verdi's Rigoletto in Bergamo. The production was considered a failure, and this was blamed on Gazzaniga's performance. Being quite irritated at the time, Verdi claimed that he had also disliked her performances in the premieres of Luisa Miller and Stiffelio. That same year she also performed in Bologna, singing the title role in Bellini's Norma and Paolina in Donizetti's Poliuto.
Later she went on tour to both North and Central America. On her first such tour, which began in 1857, her husband, Count Malaspina, died of smallpox on the boat to Havana. On a subsequent tour to New York (1866–1867) a critic praised her voice as having "greater purity and less vehement forcing of tone". She continued touring each year in the Americas until 1870. Near the end of her career she sang mezzo-soprano roles. For example, she relinquished the role of Leonora in Verdi's Il trovatore and sang Azucena instead.
Gazzaniga is a comune (municipality) in the Province of Bergamo in the Italian region of Lombardy, located about 60 kilometres (37 mi) northeast of Milan and about 15 kilometres (9 mi) northeast of Bergamo.
Gazzaniga borders the following municipalities: Albino, Aviatico, Cene, Cornalba, Costa di Serina, Fiorano al Serio, Vertova.
Traces of human presence in the Bronze Age have been found in Gazzaniga. The first document attesting the existence of a burgh (castle) dates from 476 AD, when the Barbarian king Odoacer ransacked it. In the Middle Ages Gazzaniga was part of the Confederazione de Honio together with neighbouring communes; in 1397 Gazzaniga was destroyed by the Ghibellines, and again by the Guelphs in the next year.
Later Gazzaniga was in the possession of the Republic of Venice. In 1629 Gazzaniga suffered from a plague.
