The Greek Women's Water Polo A1 League (Greek: Ελληνικό Πρωτάθλημα Υδατοσφαίρισης της Α1 Γυναικών) is the premier championship for women's water polo teams in Greece.

The champion, the runner-up and the third-placed team qualify for the LEN Euro League.

In the next five years, Olympiacos Piraeus and Vouliagmeni were alternating at the top of the championship, but in the last decade Olympiacos Piraeus has been completely dominated.

Olympiacos Piraeus have won the most championships (15), while being also the current champion (2023–24).

Greek clubs are among the most successful in European water polo.
