2017–18 National League

The 2017–18 National League season, known as the Vanarama National League for sponsorship reasons, was the third season under English football's new title of National League, 14th season consisting of three divisions and the 39th season overall.

The National League covers the top two levels of non-League football in England. The National League is the fifth highest level of the overall pyramid, while the National League North and National League South exist at the sixth level. The top team and the winner of the play-off of the Premier division will be promoted to English Football League Two, while the bottom four are relegated to the North or South divisions. The champions of the North and South divisions will be promoted to the Premier division, alongside the play-off winners from each division. The bottom three in each of the North and South divisions are relegated to the premier divisions of the Northern Premier League, Isthmian League or Southern League.

This is the first season to include six teams in the play-offs for each division, with the 4th-7th placed teams participating in the qualifying round and the 2nd and 3rd placed teams qualifying for the semi-finals.
