Charles "Chuck" Blazer (born 26 April 1945) is an American soccer administrator.
He has been a member of the FIFA Executive Committee since 1996, and served as Commissioner of the American Soccer League and Executive Vice President of the United States Soccer Federation. He is currently the General Secretary of CONCACAF.
In May of 2011, in response to allegations of bribery made by national representatives attending a 10 May meeting of the Caribbean Football Union (CFU), Blazer initiated an investigation of AFC President Mohammed bin Hammam and FIFA Vice President Jack Warner. The investigation was conducted by John P.Collins, former United States federal prosecutor and FIFA Legal Committee member. Its submission led to FIFA's 29 May 2011 suspension of Warner and Bin Hammam from all soccer activities pending the outcome of FIFA's own investigation and procedures. Acting CONCACAF president Lisle Austin attempted to fire Blazer five days later, but the action was blocked by the CONCACAF executive committee. On 15 June 2011, Blazer was questioned by FIFA's ethics committee.
