Numerous horse-drawn tramroads were constructed in South Wales during the Industrial Revolution, chiefly between the years 1790 and 1830 and connected with the iron and coal-mining industries.

The earliest tramroads were "edge-railways", where the wagons were guided by having flanged wheels running on plain rails, but from around 1800 most tramroads in the area were being made according to the principles of Benjamin Outram, with unflanged wheels running on L-section tracks fixed to stone-block sleepers; and many earlier lines were also rebuilt to these specifications. An unlikely achievement: the development of the edge railway for general freight and passengers; Carolyn Dougherty, 2005 Track gauges were not standardised, but most were between .

Overall, the early railways in South Wales covered about , but between the 1840s and the 1860s most of the main lines were replaced by standard-gauge steam railways.

The list of tramroads in South Wales can be split into a number of regions:

Monmouthshire and Brecon Canal network The canals converging on Newport Docks originally comprised two independent canals: the Monmouthshire Canal between Newport and Pontymoile Basin (as well as the Crumlin Arm, and the Brecknock and Abergavenny Canal between Pontymoile and Brecon.

Numerous tramroads, some built by the canal companies themselves, converged on these canals, as well as forming cross-country routes not directly linked to the Monmouthshire and Brecon Canal network:
