Luton needed only to equal the result of Exeter who had gained a point after a 2-2 draw with Crawley, and they managed to do so with 1-1 draw with Carlisle United to secure their promotion.
Carlisle's Danny Grainger put the hosts ahead before half-time, but Olly Lee equalised after the break to secure that all important point.
They have a combined total of 91 goals this season, only three goals behind Premier League champions Manchester City.
Their promotion to League One will mark the first time in ten years that the 'Hatters' have managed to break back into the top three tiers.
Luton were relegated to League Two back in April 2008, before dropping out of the Football League entirely the following season, predominantly as a result of financial difficulties.
The club saw themselves being deducted an unprecedented 30 points for entering administration for the third time within a ten year period.
