The newlywed is the first to hold the title of Baron Carrickergus since 1883, and residents of the Co Antrim seaside town are hopeful the honour could mean a royal visit.
Mayor Jim McClurg said: "It's an extreme thrill for the people of Carrickfergus to have this honour bestowed on them. It's taken us completely by surprise."
"We certainly hope this means we can expect a special royal visitor in the near future."
The Union Jack was raised at the town's Norman castle before the wedding got underway at 11am.
County Antrim's oldest town is also the site where William of Orange landed more than 300 years ago.
Thrilled Carrickfergus residents are hopeful Prince William will visit in less dramatic circumstances than his namesake.
It's a big honour and it's a lot to stand to but I think he is more than capable.

Another resident told UTV: "She is a beautiful girl and he is my number one."
The celebrations in Carrickfergus were one of many held across Northern Ireland in honour of Friday's royal wedding, as the country enjoyed a day of pageantry and fun, which will long be remembered.
Prince William has been made the Duke of Cambridge on his wedding day by his grandmother the Queen, Buckingham Palace announced early on Friday.
Catherine became Her Royal Highness the Duchess of Cambridge.
William also became the Earl of Strathearn and Baron Carrickfergus, with his wife now known as the Countess of Strathearn and Baroness Carrickfergus.
