"To President Carter, I want to issue a sincere apology. It is no longer fair to say he was the worst president of this great country in my lifetime. President Obama has proven me wrong," 42-year-old Jindal told a conservative political action committee on Thursday.
In his address, Jindal criticised Obama on his foreign policy front at a time when the Russia has taken military action in Ukraine.
"I spent a lot of 2012 going around the country saying that President Obama was the most liberal and most incompetent president in my lifetime, ever since Jimmy Carter," the Republican leader said.
"Seeing a president that doesn't understand that a strong America leads to a peaceful, more stable world, seeing a president who doesn't understand that a weak America leads to instability, seeing a president who doesn't seem to understand that our allies and our enemies alike need and want a strong America," said Jindal, who is widely being seen as a potential Republican presidential candidate.
In his speech marked with applause and laughter, Jindal also criticised the economic and domestic policies of Obama.

"This President graduated from some of the best schools in the country. If I were him - and if he would like some free advice - if I were him, I'd consider suing Harvard Law School to get his money back because I'm not sure what he learned in three years," Jindal said amidst cheers and applause.
"This administration has assaulted our religious liberties. It has assaulted the American Dream. It's trying to redefine the American Dream so that success is defined by government assistance. That's not the American Dream; that's an American nightmare."
