Olympiacos women's basketball

The Olympiacos women's basketball team is the women's basketball department of the major Greek multi-sport club Olympiacos CFP, based in Piraeus. The department was initially founded in 1947, being one of the best women's basketball clubs in Greece during the 1950s and the early 1960s, when they won 3 Women's Division Center Championships (1956, 1958, 1959), which was the most important competition of Greek women's basketball at the time (until 1967–68 when the Greek Women's Basketball League was officially organized). The department was dissolved in the mid-1960s and after a long period of inactivity, it was reorganized in 2015.

Olympiacos is one of the most successful clubs in Greek women's basketball history, having won 8 Greek League championships, a record 5 Greek Cups and a record 5 Doubles. From the start of the 2015–16 season (which was the first after its reorganization), till the 25th of October 2020, Olympiacos remainded undefeated in all official or friendly games in all domestic competitions (for more than 5 years), setting a world record of 137 consecutive victories (118 of which were in the Greek League), and winning 5 consecutive undefeated Greek League championships (2016, 2017, 2018, 2019, 2020) and 4 consecutive undefeated Doubles (2016, 2017, 2018, 2019 –the 2020 Greek Cup was not completed due to the COVID-19 pandemic–). The world record of 137 straight wins was finally stopped on October 25, 2020, during the 2020–21 Greek League.
