The 2011 World Rowing Championships were World Rowing Championships that were held from 28 August to 4 September 2011 at Lake Bled, adjoining the Slovenian city of Bled. The annual week-long rowing regatta is organized by World Rowing Federation (FISA), and held at the end of the northern hemisphere summer. In non-Olympic Games years the regatta is the highlight of the international rowing calendar, and in the year prior to the Olympics it is the main qualification event for the following year's Olympics.
