The 2003 WNBA Season was the Women's National Basketball Association's seventh season. It was first season in which teams either folded or relocated, as well as the first to have teams that were not co-owned with NBA teams. The Orlando Miracle relocated to Connecticut and became the Connecticut Sun, the Utah Starzz relocated to San Antonio, Texas and became the San Antonio Silver Stars. Meanwhile, both the Miami Sol and the Portland Fire folded, while the Charlotte Sting became the second WNBA team without a brother NBA team. The schedule increased from 32 games per team to 34. The season ended with the Detroit Shock winning their first WNBA Championship.
