The 2011 Portland Timbers season was the debut season for the Portland Timbers in Major League Soccer (MLS), the top flight professional soccer league in the United States and Canada. As the fourth incarnation of a professional soccer club to bear the Portland Timbers name, the MLS version of the Timbers began the 25th season in club history with three games on the road due to ongoing renovations to Jeld-Wen Field.
The club's first game was played at Dick's Sporting Goods Park versus Colorado Rapids on March 19, which the Timbers lost 3–1. The first MLS match in Portland was on April 14 when the Timbers bested the Chicago Fire by a scoreline of 4–2 in front of a sold-out crowd of 18,627 at newly renovated Jeld-Wen Field.
