The Epsilon Team (Greek: Ομάδα Έψιλον, romanized: Omada Epsilon) is an alleged secret society that appears in Greek modern folklore, conspiracy theories and ufology. The team was first described in a 1977 book, and supposedly consists of prominent Greek people who possess secret knowledge of extraterrestrial origin. Beginning in the 1980s, literature about the society became infused with anti-Semitic conspiracy theories, placing the Epsilon Team in a cosmic battle against the Jews. The body of beliefs related to the Epsilon Team has been labeled epsilonism, and those who subscribe to it have been labeled epsilonists.
