Which WNBA teams have the most championships?

The WNBA has seen various changes to its playoff and championship formats since its inception in 1997, aimed at improving competition and fairness. Initially, the championship was determined by a single game, but in 1998, the league shifted to a best-of-three series. From 2005 to 2024, the Finals were contested in a best-of-five format, before transitioning to a best-of-seven series starting in 2025.

Throughout its history, the WNBA has crowned several champions, with the Houston Comets, Minnesota Lynx, and Seattle Storm each winning four titles, the highest in league history. Other notable teams include the Detroit Shock, Las Vegas Aces, Los Angeles Sparks, and Phoenix Mercury, each with multiple championships. The Golden State Valkyries made history in 2026 by becoming the first expansion team to win a title within its first two seasons.
