The 2011 Novak Djokovic tennis season is widely regarded as one of the greatest seasons ever in men's tennis. He ended the year with an impressive 10–1 record against Rafael Nadal and Roger Federer, the other two best players of the year. From the start of the year, he went undefeated until the French Open semifinals in June (losing to Federer), compiling a 41-match winning streak. Djokovic won ten tournaments, in which three of them were Grand Slam events: the Australian Open, Wimbledon Championships and the US Open. He won a then record (since broken by himself) five Masters Series 1000 titles: Indian Wells, Miami and Canada, played on hard courts, and Madrid and Rome, on clay. Djokovic also won in Dubai and at the Serbia Open. 

Djokovic won seventy matches and lost only six (including two in which he retired due to injury). He beat Nadal in six finals during the season and reached the world No. 1 ranking for the first time on 4 July, maintaining the top ranking for the rest of the season. Among the six finals he defeated Nadal, two were in Masters tournaments on clay: a notable reversal due to the fact that he had lost all nine matches played against Nadal on clay prior to this season. He also set a new season record by winning $12.6 million USD in prize money on the ATP World Tour. Furthermore, he obtained a 21-4 record against top-10 and a 13-3 against Top-5 players.

Australian Open

In the last week of January, Djokovic took on the four-time and reigning champion Roger Federer. The first set was won in a tiebreaker, which went to Djokovic in seven-points-to-three. In the second set, Djokovic took an early break of serve, when Federer overhit his backhand shot. But Djokovic let Federer gain control and Federer broke twice to take a four-games-to-two lead. In a pivotal ninth game, Federer was serving for the set, but hit an ineffective drop shot that allowed Djokovic back into the set. In the eleventh game, Federer again lost serve, paving the way for Djokovic to go up two-sets-to-none. Federer broke Djokovic in the eight game of the third set to level it at four-games all, but Djokovic broke again in the ninth game. This allowed Djokovic to serve out the match.

In the final, Djokovic took on Andy Murray, with Murray coming under serious duress in the second game, when he had to survive a 14-minute service game. Murray held serve at this key juncture, and the first set stayed on serve until the tenth game.

Djokovic took the break of serve on the subsequent point, and captured the first set in a hard-fought 59 minutes.

Analysis
Tennis Magazine ranked it the third Greatest tennis season of the Open Era, behind Roger Federer's 2006 and Rod Laver's 1969. Pete Sampras hailed Djokovic's 2011 season as the best he has ever seen in his lifetime, calling it "one of the best achievements in all of sports." Boris Becker called Djokovic's season "one of the very best years in tennis of all time," adding that it "may not be the best statistically, but he's beaten Federer, he's beaten Nadal, he's beaten everybody that came around to challenge him in the biggest tournaments in the world." Rafael Nadal, who lost to Djokovic in six finals on three different surfaces, described Djokovic's performances as "probably the highest level of tennis that I ever saw."

Djokovic's performance improved on all grounds compared to the previous year, especially on his return games, with the efficiency of his second serve return points (overall 58%) leading him to the season best return games won statistics (39%).  Justin Gimelstob attributed Djokovic's consistency to the improvement in his service game, particularly when it came to his second services, which was just one percent behind of those statistic leaders like Nadal and Federer. According to him Djokovic's strength derived from his agility, his backhand and his return of serve, which was the best on the 2011 tour.
