National League South 2015-16

The 2015–16 National League South season, known as the Vanarama National League for sponsorship reasons, is the first season under the new title of National League, twelfth season consisting of three divisions and the thirty-sixth 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, whilst 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 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.

On 6 April 2015, it was announced that as of the 2015–16 season the League was to undergo a name change from the Football Conference to the National League. As well as the name change, the league's logo has been re-designed and the league's broadcaster BT Sport has signed a new three-year contract. The structure of the league and the title sponsor Vanarama however remain the same.
