The Spartan South Midlands Football League is an English football league covering Hertfordshire, north-western 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) of the National League System, divisions One and Two at step 6/level 10 and step 7/level 11 of the National League System respectively. The reserve divisions are not part of the National League system.
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|
In 1998, the geographic sections were abolished, and a simple three-tier structure with promotion and relegation between the divisions was introduced.
