The Welsh Football League Division Two, (currently the Nathanielcars.co.uk Welsh League Division Two, for sponsorship reasons) is a football league and forms the third level of the Welsh football league system in South Wales.
If the team which finishes top of the division has good enough ground facilities, it is promoted to the Welsh Football League Division One and is replaced by the team finishing bottom of Division One. The team finishing in bottom position is relegated to the Welsh Football League Division Three.
Since its inception in 1904 it has always sat below the top flight of the Welsh League, or the Rhymney Valley League and Glamorgan League as it was known until 1912.
This division has changed its title on numerous occasions to follow suit of the other leagues within the competition; for seven years in the 1980s it was known as the Premier Division as the top flight adopted the National Division name, while Division Two was split into two sections - A & B and West & East - for a large number of years before 1965.
In 1992 it became level three of the Welsh Football Pyramid following the creation of the Welsh Premier League.
