A constitutional doctrine that permits facial invalidation of a statute regulating speech when the law prohibits a substantial amount of protected expression judged against its plainly legitimate sweep. The challenger may prevail without showing the statute is unconstitutional as applied to the challenger's own conduct. The doctrine rests on the risk that an overbroad law will chill protected speech by persons not before the court.
Otis Olsen stands in a public airport terminal handing out religious pamphlets to arriving passengers. Airport police cite a resolution that bans all First Amendment activities in the terminal. A court applies the overbreadth doctrine and strikes the resolution down because the prohibition reaches virtually every form of protected expression far beyond any narrow security or traffic objective.
Otis Olsen stands on a sidewalk criticizing an officer during an arrest and is cited under an ordinance banning any speech that interrupts police in any manner. He challenges the ordinance facially. The court applies the overbreadth doctrine and invalidates the law because it reaches a substantial amount of protected speech beyond its legitimate applications.

Odin Obeng goes door-to-door in a residential neighborhood to discuss political and religious causes without first obtaining a permit. City officials enforce an ordinance requiring every canvasser to secure a permit before any solicitation. The court rejects the facial overbreadth claim because the ordinance's legitimate applications to fraud prevention outweigh the limited protected speech it reaches.
Orson Ochoa burns a cross on the lawn of an African-American family and is charged under a city ordinance that criminalizes only those fighting words that insult on the basis of race or religion. He raises a First Amendment defense. The court invalidates the ordinance because its content-based distinction within the fighting-words category renders it facially overbroad.
Olga O'Neill posts a political sign in her yard and is cited under an ordinance banning virtually all residential signs except limited categories. She challenges the ordinance facially. The court applies the overbreadth doctrine and strikes it down because the prohibition reaches a substantial amount of protected expression beyond the city's asserted interests.
Otto Osman goes door-to-door distributing religious literature and is cited under a blanket prohibition on all solicitation. He challenges the ordinance facially. The court applies the overbreadth doctrine and invalidates the law because it unduly burdens traditional protected methods of communication including religious and political canvassing.
The challenger must demonstrate that the statute prohibits a substantial amount of protected speech relative to its plainly legitimate sweep. The overbreadth must be substantial both in absolute terms and in relation to the statute's core applications.

Yes. The doctrine permits a party whose speech may be constitutionally prohibited to challenge the statute on its face because it also threatens the protected expression of third parties not before the court.

The doctrine is strongest and most frequently invoked in free-speech cases. Courts have applied analogous reasoning to equal-protection challenges involving overbroad gender generalizations, but the classic facial-overbreadth analysis remains tied to protected expression.

Both doctrines address facial challenges and the risk of chilling protected conduct. Overbreadth focuses on the statute's excessive reach into protected speech, while vagueness concerns lack of fair notice and arbitrary enforcement. The two often overlap in First Amendment litigation.
