William Hallam (trade unionist)

William Hallam (1856 – 4 July 1902) was a British trade unionist.

Hallam came to prominence when he was elected as the checkweighman at Markham Colliery in Derbyshire in 1883, and subsequently as the colliery's delegate to the new Derbyshire Miners' Association. He was elected as president of the DMA in 1890 and served until 1898, when he was narrowly defeated by Barnet Kenyon. While in office, he wrote Miners' Leaders, an important source of information on leading figures in miners' trade unions up to that point.

Hallam contested the presidency against Kenyon each year until his death in 1902, but was never successful. He also served as the clerk to Staveley Parish Council.
