The 2003 Men's Premier Soccer League season was the inaugural season of the MPSL.
Arizona Sahuaros finished the season as national champions, beating Utah Salt Ratz in the MPSL Championship game
Three of the teams who contested the first season - Arizona Sahuaros, Chico Rooks and Northern Nevada Aces - previously competed in the United Soccer Leagues, but left to form the breakaway MPSL in protest at the way the USL was being run.
