John Doe and Jane Doe are fictitious names used in the USA, Canada, the United Kingdom, and other English-speaking countries to refer to a unknown or anonymous person. They may appear in legal documents, medical records, police reports, or news articles when the real name of a person is unknown or needs to be concealed.
Where and why they are used
- In medicine: when a patient arrives at a hospital without identification or consciousness — they are temporarily registered as John Doe (for a male) or Jane Doe (for a female).
- In forensics: the police may refer to an unidentified deceased person or suspect by these names until the identity is established.
- In courts: Doe is often used to refer to a party that cannot or should not be named for certain reasons (for example, in cases that protect privacy).
- In legal examples: “John Doe vs. State” or “Jane Doe vs. University” may be examples or real cases involving anonymous participants.
- For educational purposes: the names serve as neutral examples in law, computer science, or ethics textbooks.
Where it came from
The history of these names dates back to medieval England. In the 14th-15th centuries, fictitious parties were used in land ownership court cases — John Doe as the plaintiff and Richard Roe as the defendant. Such fictional names simplified legal procedures when discussing an abstract case without real individuals.
Over time, John Doe became a universal designation for “anyone” — especially an unknown man, while the female variant Jane Doe appeared later, around the 18th-19th centuries.
Modern meaning
Today, “John Doe” in culture has become synonymous with an ordinary, average person. In films and TV shows, this name is often used for anonymous characters or victims — for example, in the movie Se7en, John Doe is the alias of a mysterious serial killer.
