Dynamite!! 2008

'Dynamite!! 2008' was the annual kickboxing and mixed martial arts event held by K-1 & DREAM on New Year's Eve, Wednesday, December 31, 2008, at the Saitama Super Arena in Saitama, Japan. It featured eleven DREAM mixed martial arts rules fights in a variety of weight classes, four K-1 rules fights, and the inaugural K-1 KOSHIEN Under 18 high school tournament.

Canceled fights

 * An MMA bout between Mark Hunt and Jerome Le Banner was originally scheduled, but Le Banner had to withdraw a few days before the event. Melvin Manhoef was instead brought in to replace him.
 * Joachim Hansen was scheduled to fight JZ Calvancante, but the bout was canceled the day of the event due to Hansen sustaining a head injury training and not passing pre-fight medicals.

Broadcast
In Japan, parts of the event were shown live on TBS (Tokyo Broadcasting Station) in a four an hour timeslot and the full event on a delayed pay-per-view. Unlike the previous year's event, Dynamite!! did not have North American clearance in 2008.
