In popular culture and UFO conspiracy theories, men in black (MIB) are government agents dressed in dark suits, who question, interrogate, harass, threaten, unidentified flying object (UFO) witnesses to keep them silent about what they have seen. The term is also frequently used to describe mysterious men working for unknown organizations, as well as various branches of government allegedly tasked with protecting government UFO secrets or performing other strange activities. They are typically described as tall men with expressionless faces, slightly pale skin, and usually wearing black suits with black sunglasses. “Men In Black” encounters are very common tales told in American UFO conspiracy theories.

The term is generic, as it is used for any unusual, threatening or strangely behaved individual whose appearance on the scene can be linked in some fashion with a UFO sighting.^[2] Several alleged encounters with the men in black have been reported by UFO researchers and enthusiasts. The "MIB" supposedly appeared throughout different moments in history. In many American UFO lore stories, they are typically described as tall men with expressionless faces, slightly pale skin, and usually wearing black suits with black sunglasses. They often interrogate alleged witnesses and strive to suppress all evidences regarding UFOs and alien encounters.

Stories about men in black inspired the science fiction comedy franchise Men in Black and an album by the Stranglers.
