John Doe

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. 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/Johnny Doe (for children).
