The Andinia Plan () is a conspiracy theory that alleged plans to establish a Jewish state in parts of Argentina and Chile. It is partly based on an exaggeration of historical proposals for organized Jewish migration to Argentina in the late 19th and the early 20th century (which, however, did not include plans for a Jewish state there). The name and contents of the plan have wide currency on some circles of the Argentinian and Chilean left-wing and right-wing, but no evidence of its actual existence has ever been brought up, making it, according to the US-based Anti-Defamation League and the Israeli research institute Jerusalem Center for Public Affairs, an example of a conspiracy theory.
