John Doe

The names John Doe or John Roe for men, Jane Doe or Jane Roe for women, Johnny Doe and Janie Doe for children, or just Doe non-gender-specifically 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, from which the use of John Doe in a legal context originates. The names Joe Bloggs or John Smith are used in the UK as placeholder names, (mainly to mean any old person, the classic Everyman) as well as in Australia and New Zealand.
