Caroline Aparecida Trentini (born July 6, 1987) is a Brazilian supermodel.

Trentini was born in Panambi, Brazil. Trentini is the youngest daughter of Lourdes and Jacó Trentini, who died when she was one year old. Her older sisters are Franciele and Elen. Although having never worked before, Lourdes got a job as a public employee when Jacó died and raised her daughters single-handedly.

In 2000, Trentini was discovered walking down a street in her hometown by an agent, the same one who scouted Gisele Bündchen, and soon afterward she moved to São Paulo, a common destination for young Brazilian models. Her modeling career immediately took off, and after a year, Trentini moved again, this time to New York City. She did not speak English but quickly learned the new language. Trentini’s breakthrough came when designer Marc Jacobs cast her in his Marc by Marc Jacobs ad campaign, photographed by Juergen Teller.
