The Hellenic Philotelic Society (formed 1925) is a philatelic organisation in Athens devoted to promoting the philately of Greece and the Greek area.

[1] The society played an important part in the development of philately in Greece.

The society also established in the Greek language foreign philatelic terms, including philately, watermark, tete-beche and others.

The society organised some of the first national and international philatelic exhibitions in Greece and worked with state institutions to establish stamp issuing and destruction policies to protect the reputation of Greek stamps.

The society's most important publications are its Study of the Greek stamp published in Greek and French: The Philatelic Library series consists of a series of numbered booklets, now exceeding sixty, which are reprints of articles or complete studies previously published in Philotelia.
