After strong legs from Asafa Powell, Yohan Blake and Nickel Ashmeade, Bolt was handed the baton in the lead for the fourth a final leg. By the end of his 100m stint, Jamaica was out of sight.
A dominant performance (Jamaica won gold with a time of 37.27) to cap a truly remarkable Olympic career in which Bolt has won gold in the 100m, 200m and 4x100m relay at all three Olympic Games he has featured.
Speaking after the momentous win, he summed up his own legacy:
"There you go, I'm the greatest," Bolt said. "I'm going to stay up late and have fun. I never knew this would happen when I started out."
Given what he has achieved during his career, there will be few people arguing with his claim as the greatest athlete ever to grace the sport.
With Rio looking extremely likely to be his final games, it is fitting to see Bolt go out with yet another gold medal to his name.
But, while Jamaica were busy celebrating, it was a painful end to the Brazil event for Team USA.
Having seemingly claimed bronze behind a stunning run from Japan in silver, the American quartet were disqualified from the race after it emerged that lead-off runner Mike Rodgers passed the baton to Justin Gatlin outside the exchange zone.
