The American Federation of Labor (A.F. of L.) was a national federation of labor unions in the United States that continues today as the AFL–CIO. It was founded in Columbus, Ohio, in 1886 by an alliance of craft unions eager to provide mutual support and disappointed in the Knights of Labor. Samuel Gompers was elected the full-time president at its founding convention and was re-elected every year except one until his death in 1924. He became the major spokesperson for the union movement.

The A.F. of L. was the largest union grouping, even after the creation of the Congress of Industrial Organizations (CIO) by unions that were expelled by the A.F. of L. in 1935. The A.F. of L. was founded and dominated by craft unions, especially in the building trades. In the late 1930s, craft affiliates expanded by organizing on an industrial union basis to meet the challenge from the CIO. The A.F. of L. and the CIO competed bitterly in the late 1930s but then cooperated during World War II and afterward. In 1955, the two merged to create the AFL–CIO, which has comprised the longest lasting and most influential labor federation in the United States to this day.
