Peeping Tom laws—also known as voyeurism laws or invasion of privacy laws—generally make it illegal and a criminal offense to peek into windows or doors on private property to view a person who is fully or partially naked for the purpose of sexual desire or gratification.

Peeping Tom laws vary from state to state and some states require that the victim not realize he or she was being viewed and that the victim had a reasonable expectation of privacy (was in a place where it was reasonable to expect privacy). And some states specifically address the use of unmanned aircraft (drones), cameras, video cameras, and binoculars in connection with such peeping. Some state statutes specifically prohibit peeking into bathrooms, dressing rooms, showers, and baths. And some states characterize this criminal offense as trespassing with the intent to peer or peep.

Peeping Tom laws are located in a state’s statutes—often in the penal or criminal code.

In Wyoming, Peeping Tom laws are addressed under the state's voyeurism statutes. Wyoming Statute § 6-4-304 makes it a crime to invade the privacy of another person for sexual gratification without the person's consent. This includes observing, photographing, or recording a person in a state of undress or engaging in intimate acts where the person has a reasonable expectation of privacy. The law specifically prohibits such actions in private places like bedrooms, bathrooms, changing rooms, and similar areas where one would expect privacy. The use of devices such as cameras, binoculars, or other means to enhance or facilitate the viewing or recording of private moments is also covered under this statute. Additionally, Wyoming law may consider such acts as trespassing if the individual enters or remains on property without authorization for the purpose of spying or peeping. The severity of the offense can range from a misdemeanor to a felony, depending on the circumstances and whether it is a repeat offense.
