John Doe (male) and Jane Doe (female) are multiple-use placeholder names that are used in the United States and the United Kingdom 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 cannot be confirmed. 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 (or Richard)/Jane Roe, John/Jane Smith, John/Jane Bloggs, and Johnie/Janie Doe or just Baby Doe for children.
