Roger Federer won in the final 6–1, 6–3 against Nicolas Kiefer. This tournament marked the beginning of Federer's dominance on grass courts; he remained undefeated on the surface until the final of Wimbledon in 2008. Federer's subsequent 65-match winning streak on grass remains the longest tour-level winning streak on the surface for a male player in the Open Era. It was the first of a record ten singles titles won by Federer in Halle.
