At the service, UK PM Theresa May paid tribute to those who fought and gave their lives in the conflict.
"If one day can be said to have determined the fate of generations to come, in France, in Britain, in Europe and in the world, that day was the 6 June 1944," she said.
"More than 156,000 men landed on D-Day, of which 83,000 were from Britain and the Commonwealth.
“Over a quarter of a million more supported operations from air and sea, while the French Resistance carried out extraordinary acts of bravery from behind enemy lines.
"Many were terribly wounded, and many made the ultimate sacrifice that day, and in the fierce sacrifice that followed, as together our Allied nations sought to release Europe from the grip of fascism."
The Queen, who had hosted US President Donald Trump earlier in the week did not attend the event in France.
Though she had led tributes and delivered a moving speech during a ceremony in Portsmouth on Wednesday, where she thanked D-Day veterans and hailed the resilience of “the wartime generation” as world leaders honoured those who fought in World War II.
