Gate 7 (Greek: Θύρα 7, romanized: Thira 7) is the most popular association of organized fans of Olympiacos CFP.

It took its name from the homonymous gate 7 of Karaiskakis Stadium, in Piraeus, from where its hard-core fans watched the Olympiacos games.

Earlier, "SAFOP" (Association of Athenian Olympiacos Piraeus Fans) was created on Socratous Street and the "Red and White Army" behind Karaiskaki.

Even earlier, in 1957, there was the "SFOP" (Association of Fans of Piraeus Olympiacos) with an organized presence on trips to Drama and Thessaloniki, but also to other cities in Greece.

It has a total of 156 sub-links in various parts of the world, in Greece, Cyprus, America, Germany, London, California , Ireland , Bologna , Belgrade and two major Greek communities in Australia, Sydney and Melbourne.
