Federer has won 20 Grand Slam singles titles and 103 ATP Tour titles, as well as attracting legions of fans around the world.
As he prepares to retire, BBC Sport looks back at 10 iconic moments from his career and asks you to vote for your favourite.
Wimbledon 2001 – beating Sampras at age 19
Pete Sampras was the best dog at Wimbledon. In 2001 he was a four-time defending champion, number one in the world and a heavy favorite for the title.
Then, in the fourth round, he was up against a 19-year-old with a ponytail who was starting to move up the rankings.
Federer, the 1998 Wimbledon men’s champion, overcame 7-6 (9-7) 5-7 6-4 6-7 (2-7) 7-5 in three hours and 41 minutes to end Sampras’ dominance in Wimbledon. .
It would be the first of many surprising Center Court results for the Swiss great.
Wimbledon 2003 – first Grand Slam title
It was fitting that Federer won his first Grand Slam at Wimbledon, which he has often described as his favorite tournament.
Having failed to go beyond the quarterfinals in his previous major appearances, Federer dropped just one set en route to the final, where he beat Australian Mark Philippoussis 7-6 (7-5) 6-2 7 -6 (7-3).
An emotional Federer dedicated his victory to former coach Peter Carter, who died in a car accident the previous year.
“Peter was one of the most important people in my career,” he said. “I hope you saw it from somewhere.”
The win was the start of a period of dominance, with the Swiss winning 11 of his majors between 2004 and 2007.
Wimbledon 2008 – Epic final against Nadal
Federer may have lost, but the final between him and Rafael Nadal in 2008 is widely regarded as one of the greatest matches of all time.
Federer was seeking a sixth straight singles title, but Nadal had beaten him in the French Open final a few months earlier and had an 11-6 winning record over the Swiss.
Played more than seven hours due to rain delays, Federer lost the first two sets, saved two championship points in the fourth and forced a fifth before Nadal scored an impressive victory almost in the dark.
It ended Federer’s unbeaten streak of 65 matches on grass and was possibly the peak of a passionate rivalry that lasted until Federer’s retirement.
Beijing 2008 – Olympic gold in doubles
Federer arrived at the Beijing Olympics just a month after his loss to Nadal at Wimbledon and on the brink of losing his world number one spot to the Spaniard after 236 weeks at the top.
Having lost in the singles quarterfinals, he and Stan Wawrinka teamed up for the men’s doubles and scored a big win over the Bryan brothers of the United States in the semifinals.
They then beat Sweden’s Simon Aspelin and Thomas Johansson 6-3, 6-4, 6-7 (4-7) 6-3 to give Switzerland its first Olympic tennis medal since 1988.
It would be the only Olympic gold of Federer’s career.
French Open 2009 – Complete career Grand Slam
In 2009, the only thing that was eluding Federer was the French Open title. He had reached the finals in Paris for the last three years, but he had lost them all to Nadal.
Federer had scored just his second victory over Nadal on clay in the run-up to Roland Garros, but Nadal was once again the heavy favorite to lift the trophy.
However, Nadal’s shock loss to Robin Soderling in the fourth round set things in motion for Federer.
Federer seized his chance, eventually beating Soderling 6-1, 7-6 (7-1), 6-4 in the final to become only the sixth man to win all four Grand Slam singles titles.
Wimbledon 2009 – An unprecedented 15th Slam title
Federer avenged his heartbreaking loss to Nadal the year before by winning Wimbledon in 2009, but the final was just as grueling.
Federer beat Andy Roddick 5-7 7-6 (8-6) 7-6 (7-5) 3-6 16-14 in four hours and 17 minutes, with the fifth set alone lasting 95 minutes.
It was Federer’s sixth Wimbledon title and 15th major trophy, taking him past Sampras’ all-time record as the American watched from the royal box.
The victory also sent Federer back to the top of the world rankings.
Wimbledon 2012 – Beat Murray in the final
Federer entered his favorite tournament having not won a Grand Slam title since January 2010 and having eliminated in the quarter-finals in his last two SW19 appearances.
He came through a five-set match in the third round before ousting defending champion and top seed Novak Djokovic in the semifinals.
Waiting in the final was Andy Murray, who was bidding to become the first Briton since 1936 to win a major singles trophy.
But Federer crashed the party at home with a 4-6, 7-5, 6-3, 6-4 win, tying Sampras’ Open-era record of seven Wimbledon men’s singles titles and reclaiming the No. world in the process.
Murray would get his revenge a few weeks later on the same court when he beat Federer to win Olympic gold.
Davis Cup 2014 – Triumph with Switzerland
Federer had helped Switzerland to its first Davis Cup final in 22 years, but was struggling with a back injury, prompting him to withdraw from the ATP World Tour final just weeks before the main event in Lille. .
Against France, Federer lost his first singles match to Gael Monfils, leaving the tie 1-1.
He and Wawrinka teamed up for the doubles and won, and Federer was chosen to play Richard Gasquet, knowing that victory would secure the trophy for Switzerland.
Federer beat Gasquet in straight sets, causing scenes of jubilation and leading an emotional Federer to dedicate the trophy to “the boys”.
Australian Open 2017 – Shocking Grand Slam title after injury layoff
Federer arrived in Australia after spending six months out with a knee injury and with many saying he would never win a major title again.
It was not easy for Federer: he beat two top 10 players, Kei Nishikori and Tomas Berdych, and ousted Wawrinka in five sets on his way to the final, where rival Nadal awaited.
In another epic that almost inevitably went to five sets, Federer won 6-4 3-6 6-1 3-6 6-3 to claim his 18th Grand Slam title and first in five years.
It was the first time Federer, now 35, had beaten Nadal at a Grand Slam since the 2007 Wimbledon final.
Dubai 2019 – 100th ATP title
Federer became the second man after Jimmy Connors to win 100 ATP titles with his victory at the Dubai Tennis Championships in March 2019.
He beat Greek Stefanos Tsitsipas, who had finished his Australian Open title defense a few months earlier, 6-4, 6-4 to lift the trophy.
The victory came 6,600 days after his first career title in Milan, which he lifted at the age of 19.
Federer would go on to win three more trophies, with his final title coming at the Swiss Indoors in 2019.
