Alternate Returning Castaways

Alternate Returning Castaways are past contestants who were considered to return for a season, but either were not chosen or declined the offer.

Casting of alternates contains much speculation, so castaways are only included in this list if they have a reliable and trustworthy source. (themselves, producers, host etc.)

Survivor: Tonga
While not technically returning players, these two women applied for Tonga and were cast, but were replaced.
