But what has underpinned their strong start to the campaign? And where can they still improve? From defensive solidity to impressive individual performances, here are 10 notable statistics from the season so far...
5. 46 - Set-piece prowess
Cobblers are particularly strong at set-pieces, conceding only 46 shots from such situations, comfortably the lowest number in the division. They are also good at the other end, creating 7.1xG and scoring a league-high 11 goals from attacking corners, free-kicks and long throws.
6. 6 - Creative fulcrum
Mitch Pinnock is very much Town's creative hub, assisting six goals this season. Only Jamille Matt (7) for leaders Forest Green Rovers has more.
7. 37.4 - Aerial supremacy
No team in League Two wins as many aerial duels per game (37.4) as Northampton.
8. 7.4 - Centre-half dominance
That strength in the air is largely down to centre-back duo Fraser Horsfall (7.4) and Jon Guthrie (6.7), who are first and third respectively for aerial duels won by defenders per game in League Two this season.
