The National Labour Federation (NLF) was a general union representing workers in the United Kingdom. The union was founded in 1886 by Edward R. Pease of the Fabian Society, and some members of the Amalgamated Society of Engineers. It was launched with a conference in Newcastle-upon-Tyne, permitting workers of any trade to join, and any other unions to affiliate. By 1890, it had more than 60,000 members, with a particular strength in Kingston-upon-Hull, with 3,000 workers there alone. The union dissolved in 1894.
