Ted Turner, 89, will be awarded the Legion D'Honneur next week on behalf of the French President Francois Hollande this Monday.
The French commander Napoleon Bonaparte originally created the Legion D'Honneur, which is equivalent to the British Victoria Cross.
Mr Turner attends St John's Church in Purbrook, Hampshire.
He stormed the beaches of Normandy as an 18-year-old with Canadian forces, and fought for six weeks before returning to the UK. He also served in Germany, Sri Lanka, Hong Kong and Japan after the War.
His service will be attended by the Lord Mayor of Portsmouth and the president of the D-Day and Normandy Fellowship. Premier presenter Pam Rhodes, who interviewed Ted for a special Songs of Praise last year to mark 70 years since D-Day, is also attending.
The 89-year-old said: "This is a great honour that I wasn't expecting.
"I know that I'll be thinking of those who didn't make it, my friends who didn't come back from the Normandy beaches after D-Day.
"My faith has been very important to me over the years, and of course there were lots of prayers said on those days around D-Day.
"God has helped me in lots of other situations too, especially when my wife Enid died five years ago. My friends at St John's Church mean a lot to me, and I'm glad many of them will also be there for this presentation."
The French government is recognising the efforts of all surviving veterans in the D-Day Landings in Normandy by awarding them the Legion d'Honneur, and is encouraging them to apply for the award.
