Roger Federer's 2011 tennis season brought no Major victories but was not entirely unsuccessful. This year, when he turned thirty, marked a decline in his standing in the sport.

However, this season had some high points. In the French Open semifinals, Federer defeated Djokovic and ended his 43-match win streak. Also, he ended the year well by winning three straight titles, including a title at the Paris Masters, and successfully defended his title at the year-end ATP Championships.
