Dominic "Dom" Toretto is one of the three lead protagonists of the series. He appears in all of the films in the series except for 2 Fast 2 Furious, in which he was mentioned. An elite street racer, auto mechanic, and ex-convict, Dominic is the brother of Mia Toretto and former love interest and ex-boyfriend of Letty Ortiz. Dominic's crew has perpetrated many high-speed truck hijackings, stealing millions of dollars in merchandise. When he is finally apprehended by Brian, Brian lets him go free. He has spent most of his life running from the law, settling elsewhere, in Mexico, Panama, Ecuador, and Dominican Republic, where he abandoned Letty to protect her. In Fast and Furious, Dominic and Brian reunite in the wake of Letty's death to stop drug lord Arturo Braga. In Fast Five, Dominic and Brian make a plot to steal all of Hernan Reyes' money in an attempt to buy their freedom. During a talk with Brian, Dominic recalls his happy childhood with his father and Mia. Dominic, Brian, and Mia recruit many of their allies for the heist, while at the same time trying to evade capture by the ruthless DSS agent Luke Hobbs and Rio police officer Elena Neves. Hobbs and Elena become allies to Dominic after his team saves them from Reyes's men. With the help of his team, Dominic's heist is successful, and goes into hiding with Mia and Brian and starts a relationship with Elena. In Fast & Furious 6, Dominic resides in Spain with Brian and Mia, who had given birth to her and Brian's child. He is approached by Hobbs, who asks him to help take down Owen Shaw, whose second-in-command is revealed to be an amnesiac but still-alive Letty. With Elena's support, Dominic regroups with his team and tries to talk to Letty to remember him and her former friends. Through numerous actions, he eventually gains Letty's trust, and defeats Shaw. His group is given full pardons from their crimes, and they return to the United States. Elena becomes Hobbs's new partner so that Dominic can be with Letty and start anew. In a post credit scene, he would later get a call with a threatening message from a man related to Owen Shaw.

Unlike Brian, Dominic is tougher and street smart. Although he owned a red Mazda RX-7, he is more interested in the American muscle cars, owning a 900 hp Dodge Charger R/T he built with his father, on which he is especially proud of. He also owned a Buick GNX, Pontiac Bonneville Convertible, Plymouth Road Runner and a Chevrolet Chevelle SS. Dominic Toretto is portrayed by Vin Diesel.
