Albert John Hayes (February 14, 1900 – August 20, 1981) was an American labor union leader.
Born in Milwaukee, Hayes completed an apprenticeship as a machinist in the railroad shops.
He rose to become president of his union local, then in 1934 began working full-time as a representative for the Grand Lodge.
As leader of the union, he convinced it to reaffiliate to the American Federation of Labor (AFL).
In 1955, the federation became part of the new AFL-CIO, with Hayes continuing as a vice-president.
