John Doe (fictional example)

John Doe is a placeholder name commonly used in the United States to refer to an unidentified or anonymous person, especially in legal cases, medical situations, or investigations. It allows professionals to discuss an individual without revealing their true identity when it’s unknown or to protect privacy. Similarly, "Jane Doe" is used for women, and "John Roe" or "Jane Roe" in specific legal contexts. The name helps standardize references when the actual identity of the person is either not available or needs to be kept confidential.
