The Fiat Duna (Fiat Prêmio in Brazil) was a small car produced by Fiat in Brazil, based on the Fiat Uno. Unlike the European Uno, it was a sedan, rather than a hatchback, as such models were more popular in Brazil, and a wagon version was also produced.

The Duna was exported to Italy and other countries in Europe, where it was sold as an Innocenti, though not the United Kingdom, as Fiat do Brasil did not produce cars in right hand drive.

Fiat Brazil has factories in Betim and Sete Lagoas.
