This is a list of all the unanswered questions that have been asked in Lost, both explicitly and implicitly. Once a question has been officially answered on the TV show or by some other source, it will be removed from the list. This list is organized by episode, in the order that each mystery is first introduced. For a list of unanswered questions by topic, see Unanswered questions. For a list of the mysteries on the show, see Mysteries. Note that these questions should be directly tied to the narrative of the show, and specific mythological unanswered mysteries.
