Corniglia (Ligurian: Corniggia; locally Curnigia)[citation needed] is a frazione ("hamlet") within the comune of Vernazza in the province of La Spezia, Liguria, northern Italy, with a population of about 150 (in 2016).

Corniglia is mentioned in a famous novella of Giovanni Boccaccio's Decameron and in the novel The Invisible Circus by Jennifer Egan.

In 1254 Pope Innocent IV gave it to Nicolò Fieschi, who held it until 1276, when the village was acquired by the Republic of Genoa.

The only ruins in Corniglia belong to Genoese fortifications, a stronghold on a cliff plunging into the sea, which dates back to approximately 1556.

While the fictional Portorosso town in the film is set on a coast, the Pixar animation team was particular interested in Corniglia for its more remote and less tourist heavy nature.
