Anti-Corn-Law League, organization formed in 1839 to work for the repeal of the English corn laws. It was an affiliation of groups in various cities and districts with headquarters at Manchester and was an outgrowth of the smaller Manchester Anti-Corn-Law Association. Richard Cobden and John Bright were its leading figures. The league won over Sir Robert Peel to its views, and the corn laws were repealed in 1846.
