This is a list of pseudonyms, in various categories.
A pseudonym is a name adopted by a person for a particular purpose, which differs from their true name. A pseudonym may be used by social activists or politicians for political purposes or by others for religious purposes. It may be a soldier's nom de guerre or an author's nom de plume. It may be a performer's stage name or an alias used by visual artists, athletes, fashion designers, or criminals. Pseudonyms are occasionally used in fiction such as by superheroes or other fictional characters.
