Beard is an American slang term describing a person who is used, knowingly or unknowingly, as a date, romantic partner (boyfriend or girlfriend), or spouse either to conceal infidelity or to conceal one's sexual orientation. The term also refers, in some areas, to anyone who acted on behalf of another, in any transaction, to conceal a person's true identity. The term can be used in heterosexual and non-heterosexual contexts but is especially used within LGBTQ+ culture. References to beards are seen in mainstream television and films, and other entertainment.
