Fan translation (or user-generated translation) refers to the unofficial translation of various forms of written or multimedia products made by fans (Fan labor), often into a language in which an official translated version is not yet available. Generally, fans do not have formal training as translators but they volunteer to participate in translation projects based on interest in a specific audiovisual genre, TV series, movie, etc.
