"This is my last presidential term and in line with the Georgian Constitution I do not intend to run again after my term expires," Saakashvili said at a meeting of Georgian judiciary.
Pro-Western president Saakashvili came to power in the former Soviet republic on the back of the so called rose revolution in 2003.
Last November Georgia was rocked by opposition rallies for six days as protestors occupied central Tbilisi demanding Saakashvili's resignation over allegations of corruption and increasing authoritarianism.
The Georgian leader responded by sending in riot police to crack down on protestors on November 7. Over 500 people were injured, according to the U.S. group Human Rights Watch, when police used rubber bullets, tear gas and water cannons to break up the demonstrations.
Saakashvili subsequently called early elections for January and was reelected with 53% of the vote.
