John Doe (male) and Jane Doe (female) are multiple-use placeholder names that are used when the true name of a person is unknown or is being intentionally concealed.[1][2][3] In the context of law enforcement in the United States, such names are often used to refer to a corpse whose identity is unknown or unconfirmed. These names are also often used to refer to a hypothetical "everyman" in other contexts, in a manner similar to John Q. Public or "Joe Public". There are many variants to the above names, including John Roe, Richard Roe, Jane Roe, Baby Doe, and Janie Doe or Johnny Doe (for children).
