Olympiakos Piraeus

Olympiacos Football Club (Greek: ΠΑΕ Ολυμπιακός Σ.Φ.Π. ), known simply as Olympiacos or Olympiacos Piraeus, is a Greek professional football club based in Piraeus. Part of the major multi-sport club Olympiacos CFP (Olympiakós Sýndesmos Filáthlon Peiraiós, "Olympiacos Association of Fans of Piraeus"), their name was inspired by the ancient Olympic Games and along with the club's emblem, the laurel-crowned Olympic athlete, symbolise the Olympic ideals of ancient Greece. Their home ground is the Karaiskakis Stadium, a 33,334-capacity stadium in Piraeus.

Founded on 10 March 1925 and nicknamed Thrylos (Legend), Olympiacos is the most successful club in Greek football history. They have won 48 league titles, 29 Cups (19 doubles) and four Super Cups, being the record holder for all of these competitions. The club won its first European title in 2024 when its U-19 Team won the UEFA Youth League. They also hold one UEFA Europa Conference League and one Balkans Cup. It is one of the few clubs to have won over 100 trophies, having won 174 titles (81 national, 27 regional, 29 Youth and Academy, 34 others, and 3 international). As of 2018, without counting regional and other titles and without having won the Conference and Youth leagues, it was ninth in the world in total titles won by a football club. The club's dominating success is further evidenced in that all other Greek clubs have won a combined total of 41 league titles while Olympiacos also holds the record for the most consecutive Greek League titles won, with seven in a row in two occasions (1997–2003 and 2011–2017), breaking their own previous record of six consecutive wins in the 1950s (1954–1959), when Olympiacos was unequivocally nicknamed Thrylos (Greek: Θρύλος, "Legend"). Having won the 2014–15 League title, Olympiacos became the only football club in the world to have won five or more consecutive championships five times in their history. They are also the only Greek club to have won six consecutive national Cups (1957–1963) as well as six League titles undefeated (1937, 1938, 1948, 1951, 1954, 1955). Olympiacos are one of only three clubs to have never been relegated from the top flight of Greek football, and by winning the 2012–13 title, their 40th in total, they added a 4th star above their crest, each representing 10 league titles.

At the international level, Olympiacos is the only Greek football club in history to have won a major European trophy by winning the UEFA Conference League in 2023–24. With their historic 2024 triumph, they became the first club outside Europe's top four leagues (Premier League, La Liga, Serie A, Bundesliga) to win a UEFA competition since 2011, and the first European club ever to win two UEFA trophies in a single season, following their youth team's earlier victory in the UEFA Youth League. Olympiacos is also the highest ranked Greek club in the UEFA rankings, placing 33rd in the ten-year ranking, and 37th in the five-year ranking as of 2025. Additionally, they are one of the founding members of the European Club Association.
