The 1998 Algarve Cup was the fifth edition of the Algarve Cup, an invitational women's association football tournament. It took place between 15 and 21 March 1998 in Portugal with Norway winning the event for the fourth time in its history defeating Denmark, 4-1, in the final-game. The United States ended up third defeating Sweden, 3-1, in the third prize game.[1]
The United States returned to the tournament, replacing Iceland.
The eight invited teams were split into two groups that played a round-robin tournament. On completion of this, the fourth placed teams in each group would play each other to determine seventh and eighth place, the third placed teams in each group would play each other to decide fifth and sixth place, the second placed teams in each group would play to determine third and fourth place and the winners of each group would compete for first and second place overall.
Points awarded in the group stage followed the standard formula of three points for a win, one point for a draw and zero points for a loss.
