Loitering is the act of remaining in a particular public place for a protracted time. Under certain circumstances, it is illegal in various jurisdictions.

Loitering may be prohibited by local governments in several countries. Loitering prohibitions are particularly common in the United States, the United Kingdom, France and Greece, although they are used throughout the world.

Loitering laws are often tracked back to late 15th century English common law
