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 Vermont, Peeping Tom laws are addressed under the state's voyeurism statute, which is found in Title 13 of the Vermont Statutes Annotated. The law makes it illegal to secretly observe or film another person without their consent when that person has a reasonable expectation of privacy. This includes situations where a person is fully or partially undressed, such as in bathrooms, changing rooms, or in their own home. The law also covers the use of any device like cameras or drones to commit such acts of voyeurism. It is a criminal offense that can lead to serious penalties, including fines and imprisonment. The intent of the voyeur, particularly if it is for sexual gratification, is a key element of the offense. Vermont's approach to Peeping Tom activities reflects a broader concern for privacy and the protection of individuals from invasive and unwanted observation.
