The 2004 WNBA Season was the Women's National Basketball Association's eighth season. The league had one fewer team than in 2003 as the Cleveland Rockers folded after the 2003 season. The season ended with the Seattle Storm winning their first WNBA Championship, as their head coach Anne Donovan became the first female coach to win a WNBA championship.
