Group A of the 2003 FIFA Women's World Cup was one of four groups of nations, consisting of Nigeria, North Korea, Sweden and the United States. It began on September 20 and ended on September 28. Defending champions and host United States topped the group with a 100% record, joined in the second round by Sweden, who overcame their defeat in the first game to qualify for the knockout stage.
Three of these teams had also been also drawn together in Group A of the previous World Cup in 1999 (the exception was Sweden, whose place was taken by fellow Scandinavians Denmark). The four teams were then drawn together in Group B at the 2007 World Cup.
