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 Alaska, Peeping Tom laws are addressed under the state's invasion of privacy statutes. Alaska Statute § 11.61.123 specifically criminalizes the act of viewing, photographing, or recording another person without their knowledge and consent in circumstances where the person has a reasonable expectation of privacy. This includes situations where a person is nude or partially clothed, such as in bathrooms, changing rooms, or their own home. The law in Alaska does not require the victim to be unaware of being viewed for the offense to occur. It is also important to note that Alaska's laws have been updated to include the use of electronic devices, such as cameras and drones, in the act of voyeurism. The offense is considered a serious invasion of privacy and is treated as a misdemeanor or felony depending on the circumstances, including the age of the victim and the nature of the offense.
