John Daly (born 1930 or 1931) is a former British trade union leader.
Daly began his career working for the National Union of Tailors and Garment Workers, and also served as a Trades Union Congress (TUC) education officer. In 1968, he moved to work for the National and Local Government Officers' Association (NALGO), spending time in each of the health, gas, and local government sections. He was chosen as an assistant general secretary of the union in 1976 and progressed to deputy general secretary in 1982.
When Geoffrey Drain, general secretary of NALGO, announced his intention to retire in 1983, Daly was the strong favourite to succeed him. He only narrowly defeated John Ward of the First Division Association, the two both placing well ahead of Alan Jinkinson, Campbell Christie and Ernest Baxendale. In the same year, he was elected to the General Council of the TUC.
Daly retired in 1989, and was succeeded by Jinkinson.
