What is Roger Federer's longest winning streak in singles matches?

Roger Federer’s longest winning streak in singles matches was 41 matches. He produced the run across 2006 and 2007, during the peak of his dominance on the ATP Tour.

The streak began at the 2006 US Open and continued through several tournaments, including the 2006 season-ending championships and the start of the 2007 campaign. Federer’s run ended at the 2007 Indian Wells Masters, where Guillermo Cañas defeated him.

The figure is sometimes confused with Federer’s much longer streaks on individual surfaces. He won 65 consecutive matches on grass between 2003 and 2008 and 56 straight matches on hard courts between 2005 and 2006. Those are surface-specific records, whereas 41 matches is his longest general singles match-winning streak.

Federer’s 41-match run ranks among the longest in the Open Era, although it was not the all-time record. Guillermo Vilas, Ivan Lendl, Novak Djokovic and others recorded longer streaks, depending on the statistical scope used.
