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.
A. N. Other is also a placeholder name, mainly used in the United Kingdom, which is gender neutral.
In Roblox, John Doe and Jane Doe are officially test accounts created by David Baszucki and Erik Cassel, two Roblox CEOs, and are listed as user/2 and user/3 in the Roblox players list.
