National Amalgamated Labourers' Union

The National Amalgamated Labourers' Union (NALU) was a trade union representing unskilled labourers in the United Kingdom.

The union was founded in 1889, initially based in Cardiff, and later in Swansea. Its membership long varied between 3,000 and 4,000, although by the 1910s, it was over 5,000.

The union affiliated to the National Transport Workers' Federation, and in 1922 it merged into the Transport and General Workers' Union.
