Roger Federer won 20 Grand Slam singles titles. His total came from six Australian Open titles, one French Open title, eight Wimbledon championships, and five US Open titles. He completed the career Grand Slam by winning the French Open in 2009, defeating Robin Söderling in the final.
Federer’s first major arrived at Wimbledon in 2003, beginning a period of extraordinary dominance. Between 2004 and 2007, he won 11 of the 16 Grand Slam tournaments, and he reached 10 consecutive major finals from 2005 through 2007. His 20th and final major title came at the 2018 Australian Open, where he defeated Marin Čilić in five sets.
A common mix-up is confusing Grand Slam singles titles with Federer’s overall tournament victories. He won 103 ATP singles titles, but only 20 of those were the four major championships. His total was later surpassed by Rafael Nadal and Novak Djokovic, but 20 remains the canonical count for Federer’s Grand Slam singles career.
