The National Guard (Greek: Εθνοφυλακή, romanized: Ethnofylakí) is part of the Hellenic Army and are voluntary corps, mainly located in areas near the frontiers, consisted of trained and armed volunteer men (and since 2019 women).

[1] The first unit in the Greek army with the name of "National Guard" was established in 1843 during the early reign of Otto of Greece.

[2] Much later, in 1948, during the Greek Civil War were established the National Guard Defence Battalions (TEA), with a strongly anticommunist orientation.

Their mission was supporting the regular Hellenic Army in national defence and internal security.

Due to their hard-line right-wing orientation, the TEA were disestablished in 1982 by the government of Andreas Papandreou, and replaced with the National Guard.
