Anime that are partially or fully lost.
Notes: I’m not including series that are only missing dubs. I’m not including anime that were previously lost media but have now been found. There are many series that I have been unable to find in the MAL database and therefore have not included. And, lastly, the information in this list is sourced from the Lost Media Wiki.
