The 2009 National Lacrosse League season, the 23rd in the history of the NLL, began January 3, 2009 in Buffalo, Portland, and Sunrise, Florida, and concluded with the Calgary Roughnecks defeating the New York Titans 12—10 in the Champion's Cup on May 15, 2009 in Calgary, Alberta, Canada.

Team movement

After the 2008 season was cancelled and then reinstated, the Boston Blazers and Arizona Sting both announced that they would not participate in the 2008 season, and would return in 2009. However, in the summer of 2008 the Arizona Sting ceased operations and its players were put in a dispersal draft. The Blazers drafted former Sting and LumberJax forward Dan Dawson first overall. Just weeks prior to the start of the season, the Chicago Shamrox suspended operations due to financial troubles and the players were placed in another dispersal draft. Anthony Cosmo was selected 1st overall by the Boston Blazers in this draft. Finally, while not a franchise relocation, the Minnesota Swarm were moved from the East Division to the West Division.
