The Welsh National League (North) was a football league in north and central Wales which formed the first level of the Welsh football league system between 1921 and 1930, and was part of a short-lived plan to create a national football league in Wales during the 1930s.
The league was set up in 1921, absorbing the North Wales Coast League. It ran for nine seasons. In 1930 the majority of clubs split into two new leagues: the North Wales Football Combination and the Welsh League.
The following teams were champions of the leagues.
