The Offaly club secured their second consecutive CCFL title after a 2-1 win over Mullingar Town.
Clara Town are now back-to-back CCFL Senior Division Champions.
The Offaly club took the three points they needed in dramatic fashion thanks to a last minute penalty against title rivals, Mullingar Town.
Mullingar took the lead and with that a chance of forcing the season in to a play-off with a goal from Jason Charles.
However Robert McDonagh equalised and then Pa Smith slotted a late spot kick to seal the win and the league championship.
