Isabella Ribeiro Santoni (Portuguese: [izaˈbɛlɐ sɐ̃toˈni]; Italian: [sanˈtoni]; born 6 May 1995) is a Brazilian actress.

Isabella Santoni was born in Nilópolis, Rio de Janeiro, to teacher Ana Cristina Ribeiro.

The minimum age to start the course was 16, but Santoni called the place and convinced them to accept her at 15.

Santoni had to make some sacrifices because of her career, one of them was the request to transfer a private school to a public one, since she could not reconcile work with her studies.

Even though the teaching conditions were precarious, Santoni was able to be approved for the Federal University of the State of Rio de Janeiro (UniRio) in 2013, where she majored in theater.
