The Women's National Basketball Association's Most Improved Player Award is an annual Women's National Basketball Association (WNBA) award given since the 2000 WNBA season, to the most improved player of the regular season. The winner is selected by a panel of sportswriters throughout the United States, each of whom casts a vote for first, second and third place selections. Each first-place vote is worth five points; each second-place vote is worth three points; and each third-place vote is worth one point.
