The Independent Labour Party (ILP) was a British political party of the left, established in 1893, when the Liberals appeared reluctant to endorse working-class candidates, representing the interests of the majority. A sitting independent MP and prominent union organiser, Keir Hardie, became its first chairman.

The party was positioned to the left of Ramsay MacDonald’s Labour Representation Committee, which was founded in 1900 and soon renamed the Labour Party, and to which the ILP was affiliated from 1906 to 1932. In 1947, the organisation's three parliamentary representatives defected to the Labour Party, and the organisation rejoined Labour as Independent Labour Publications in 1975.
