The Mayors' Cup is an annual tournament featuring friendly competition among the three AYSO soccer regions of Costa Mesa and Newport Beach.
The two-day tournament culminates in a trophy and bragging rights for the next year. Each of the three regions sends their top two teams per division. These teams compete to determine one championship team per division (boys' under 10, girls' under 10, BU12, GU12, BU14 and GU14). The region with the most championship teams is declared winner of the Mayors' Cup.
Rather than staying with the region, the trophy or cup is actually housed in the city hall of the winning region. If Corona del Mar (Region 57) is victorious, the trophy will stay at the Newport Beach City Hall for the next year. If Costa Mesa (Region 120) earns the most points, the trophy will stay at the Costa Mesa City Hall for the next year. Since the players in Newport Beach (Region 97) reside in both cities, if Region 97 prevails, the trophy spends half of the year at the Newport Beach City Hall and the other half of the year in the Costa Mesa City Hall. Each region had won the cup in one of the preceding years. (2007 - Newport Beach, 2008 - Corona del Mar, 2009 - Costa Mesa)
