The North and Mid Wales Trunk Road Agent (NMWTRA; Welsh: Asiant Cefnffyrdd Gogledd a Chanolbarth Cymru) is one of the two trunk road agents in Wales.

It is responsible for managing trunk roads in North and Mid Wales on behalf of the Welsh Government.

The agent manages trunk roads in eight principal areas of the north and mid regions of Wales: the respective principal councils of Anglesey, Ceredigion, Conwy, Denbighshire, Flintshire, Gwynedd (lead authority), Powys, and Wrexham.

The National Assembly for Wales took responsibility for devolved powers on 1 July 1999,[1] as part of this process, transport was transferred from the Parliament of the United Kingdom to the National Assembly for Wales and with it responsibility for the trunk road network, including motorways.

[3] Both the North Wales Trunk Road Agency and Mid Wales Trunk Road Agency was established on 1 April 2006, and by 1 April 2012 the two bodies merged and were renamed to become the North and Mid Wales Trunk Road Agent.
