The 47-year-old Illinois senator, son of a white mother from Kansas and an African father from Kenya, mined a deep vein of national discontent, promising Americans hope and change throughout a nearly flawless 21-month campaign for the White House.
"Change has come," Senator Obama told a huge throng of cheering supporters in Chicago at a midnight rally.
Obama polled 349 electoral votes versus 173 for McCain; 270 were needed to win.
Joe Biden, the senator from Delaware who has promised to help Obama steer his agenda through Congress, will be the vice-president.
Reacting to Obama's win, Prime Minister Bruce Golding said that he has demonstrated an understanding of global issues.
"I am confident that as you set about actualising this vision, you will make this a better place for all of mankind," Golding said in his message.
The prime minister expressed the hope that developing countries like Jamaica, so often left on the periphery of the global agenda, will be part of the foreign policy framework which recognises that shared, broad-based development is the surest way to secure and maintain global prosperity and stability.
Meanwhile, Opposition Leader Portia Simpson Miller said Obama's victory signals the dawn of a new day in international politics.
"I just feel it in my bones that the world will never be the same again," Simpson Miller said.
