John Doe (male), Jane Doe (female), or J. Doe (neutral/unknown) are multiple-use placeholder names that are used in the British, Canadian, and American legal systems, 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 cannot be confirmed. These names are also often used to refer to a hypothetical "everyman" in other contexts, like John Q. Public or "Joe Public". There are many variants to the above names, including John /Jane Roe, John/Jane Smith, Joe/Jane Bloggs, and Johnie/Janie Doe or just Baby Doe for children. The gender-neutral A. N. Other is also a placeholder name, mainly used in the United Kingdom.
