Steven Asher and Emily Marshall exchanged their vows last week at the Bristol Register Office, and climbed into a limousine to hold a reception party for their 33 guests at the fast food outlet.
Steven and Emily had spent months enjoying a string of romantic McDonald's dates.
So when it came to their big day, there was only one place for the newlyweds to toast their nuptials, 'The Sun' reported.
The couple, from Lawrence Weston in Bristol, got together a year ago before Steven proposed six months later after a string of dates.
"It was an amazing day. I did get quite a few people staring at me in McDonald's but I didn't care - it was my big day and I was there to enjoy myself," 21-year-old Emily added.
