John Doe

The names "John Doe" for males and "Jane Doe" or "Jane Roe" for females are used as placeholder names for a party whose true identity is unknown or must be withheld in a legal action, case, or discussion. The names are also used to refer to a corpse or hospital patient whose identity is unknown. This practice is widely used in the United States and Canada, but is rarely used in other English-speaking countries including the United Kingdom itself, from where the use of "John Doe" in a legal context originates. The name Joe Bloggs is used in the UK instead, as well as in Australia and New Zealand.
