The 2003 season of the ASFA Soccer League (now known as the FFAS Senior League) was the twenty third season of association football competition in American Samoa.[http://www.rsssf.com/tablest/amsamoachamp.html American Samoa - List of Champions]{{dead link|date=February 2023|bot=medic}}{{cbignore|bot=medic}} at RSSSF.com Manumea FC apparently won the championship, their first recorded title, with the winners of the 1998 league competition and a number of previous seasons unknown, however details of the season are not available and this is derived from a comment made by Prime Minister Tuilaepa Aiono Sailele Malielegaoi that a public holiday would be announced if they won the 2005 OFC Club Championship.[https://www.rsssf.org/tablesa/amsamoa03.html American Samoa 2003] at RSSSF.com
