Early life
Mathis was born in Williamsburg, Brooklyn, New York City, the daughter of Donald Mathis and Austrian-born actress Bibi Besch. Her parents divorced when she was two years old, and Mathis was brought up by her mother. She relocated with her mother to Los Angeles, California, at the age of five.

Besch tried to discourage Mathis from pursuing acting, but growing up on locations, in theaters, and in acting classes, Mathis knew she wanted to act. She decided to become an actress at the age of twelve.
