The FA Women's National League South is a league in the third level in the women's football pyramid in England, along with the Northern division. These two divisions are part of the FA Women's National League and below the Women's Super League and Women's Championship.
The league is played on a home and away basis, with each team playing each other twice, and points being awarded in the standard three points for a win format. The bottom two clubs are relegated, also on a geographical basis, to the Division One South West, and Division One South East.
For the 2023/24 season, changes were made meaning that two clubs would be relegated from the Women's Championship allowing one team each from National League North and South to be promoted to the Championship rather than having to play a season end playoff. This change resulted in two teams being relegated from the Championship at the end of the season.
Southern Premier Division teams are eligible to play in the Women's National League Cup as well as the Women's FA Cup.
