The Welsh Football League (also known as the Nathaniel Car Sales Welsh Football League for sponsorship reasons) was a club football league in Wales. For its final season in 2019–20 season it operated at levels 3 and 4 of the Welsh football league system. Level 3 – the Welsh Football League Division One and level 4 Welsh Football League Division Two. It folded in 2020 after the Football Association of Wales took over the running of tier 3 leagues and the responsibility for tier 4 passed to regional football associations.
The Welsh Football League's history stretches back to 1904 when the competition was first formed and Aberdare were crowned first champions of a seven-team First Division. Abergavenny were champions of Division 2 and Trelewis the winners of Division 3.
