In Fast & Furious, what is the name of Dominic Toretto's sister?

Dominic Toretto's sister in the Fast & Furious franchise is Mia Toretto.

Mia is introduced in The Fast and the Furious as a member of the Toretto household and the sister of Dominic. Jordana Brewster plays her throughout the main film series, including her relationship with Brian O'Conner.

Mia is not simply a background family member. She is involved in the original crew's garage and racing world, and her relationship with Brian becomes one of the franchise's continuing emotional storylines. She later becomes the mother of Brian and Jack, her children with Brian O'Conner.

Viewers sometimes mix Mia up with Letty Ortiz because both are closely connected to Dom's crew. Letty is Dom's partner, while Mia is his sister. Hattie Shaw is another recurring female character, but she belongs to the Shaw family and is not related to the Torettos.
