The Spartan South Midlands Football League is an English football league covering Hertfordshire, northwest Greater London, central Buckinghamshire and southern Bedfordshire. It is a feeder to the Southern Football League or the Isthmian League, and consists of five divisions – three for first teams (Premier Division, Division One and Division Two), and two for reserve teams (Reserve Division One and Reserve Division Two).
The Premier Division is at step 5 (or level 9) and Division One at step 6 (level 10) of the National League System (NLS) respectively. Division Two, at level 11, and the reserve divisions are not part of the NLS.
History
The league was formed in 1997 by the merger of the Spartan League and the South Midlands League. It is also known as the Molten Spartan South Midlands Football League after its sponsors.

Divisional champions
1997–98
For the league's first "transitional" season, the members of the amalgamating leagues were split into three tiers, "Premier", "Senior" and "Division One". The top and bottom tier were split geographically into North and South Sections.
| Season | Premier North | Premier South | Senior | One North | One South | 
|---|---|---|---|---|---|
| 1997–98 | Brache Sparta | Brook House | New Bradwell St Peter | Luton Old Boys | Old Roan | 
1998–2001
In 1998, the geographic sections were abolished, and a simple three-tier structure with promotion and relegation between the divisions was introduced.
