Carjacking is a type of robbery in which the criminal uses force or the threat of force to take possession and control of an automobile—usually when the victim is inside or near the automobile. Carjacking laws vary from state to state, and are usually located in a state’s penal code. Carjacking is also a federal crime when the stolen vehicle is transported, shipped, or received in interstate or foreign commerce (generally, transported across state lines).

In Wyoming, carjacking is considered a serious criminal offense and is addressed under the state's robbery statutes. Wyoming Statutes define robbery as the felonious taking of personal property in the possession of another, from his person or immediate presence, and against his will, accomplished by means of force or fear. While Wyoming law does not have a specific statute labeled 'carjacking,' the act of taking a vehicle through force or threat of force would fall under the general robbery statutes. The severity of the punishment for robbery, which would include carjacking, can vary based on the circumstances of the crime, such as the use of a deadly weapon or bodily injury to the victim. Additionally, carjacking becomes a federal crime if the stolen vehicle is transported across state lines, which falls under the jurisdiction of federal law enforcement and is prosecuted in federal court. This federal aspect is governed by the Hobbs Act or the Federal Carjacking statute (18 U.S.C. § 2119), which specifically addresses carjacking and prescribes penalties for such offenses involving interstate or foreign commerce.
