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 Louisiana (LA), Peeping Tom laws are addressed under the state's criminal statutes, specifically under the crime of 'Video Voyeurism.' Louisiana law makes it illegal to view, photograph, or film another person without their consent in a setting where the person has a reasonable expectation of privacy, such as in a bathroom, dressing room, or bedroom. This applies to situations where the person is nude or partially clothed and where the intent is for sexual gratification. The law also covers the use of devices like cameras and drones to commit such acts of voyeurism. Additionally, Louisiana law prohibits trespassing on private property with the intent to engage in peeping. Violations of these laws can result in criminal charges ranging from misdemeanors to felonies, depending on the circumstances and the presence of any aggravating factors, such as prior offenses or the age of the victim.
