The Greek women's Basketball League, also known as A1 Ethniki (A1 National) Women's Basketball is the most important competition of Greek women's professional basketball. It is organised by the EOK (Hellenic Basketball Federation). It began with the 1967–68 season. The first championship of the league, which was held in the 1967–68 season, was organised by ΕΟΑΠ (Greek: Ελληνική Ομοσπονδία Αθλοπαιδιών). Two years later, the EOK assumed control of the competition.
Iraklis Thessaloniki won the first championship of the league, in the 1967–68 season. From 1976 to 1999, Sporting Athens dominated the competition, winning 20 championships in that period (they also won another championship in 2004). So far, Sporting has won the most league championships (21 in total). From 2008 to 2012, Athinaikos dominated exclusively, breaking the record of consecutive wins in the Greek Women's League. The successes of Olympiacos were entered into the Guinness book of records. The consecutive win streak of Olympiacos was finally stopped at 117 wins. The current champion of the league is Olympiacos, which has won the last five league championships.
The Greek Women's Basketball League competition started in 1968. In the 1984–85 season, the competition was renamed to A National, and in the 1997–98 season, it was renamed to A1 National. Simultaneously, the second division was created under the name A2 National. In 2010, the organisers of the league championship decided to add playoff rounds to the competition.
