The Cumberland Miners' Association was a trade union in the United Kingdom.
The union was founded in 1872 as the West Cumberland Miners' Association, with its aims being the establishment of an eight-hour day, and improved safety.
[1] Never a large organisation, in 1910 it had 6,326 members, based in Whitehaven and Workington.
[2] Its executive became dominated by the Independent Labour Party, and it thereby came to have considerable influence in elections in the county, with most Labour Party candidates being union members.
In 1945, the CMA became the Cumberland Area of the National Union of Mineworkers (NUM), with less autonomy than before.
