The couple looked nervous but happy and got through their vows without stumbling before Archbishop of Canterbury Rowan Williams pronounced them husband and wife.
A million well-wishers - as well as some protesters - flooded into the historic environs surrounding Buckingham Palace, Westminster Abbey and other London landmarks.
"Will, it's not too late!" said one sign held aloft by an admirer dressed as a bride.
About 1,900 guests were attendance, including soccer star David Beckham and musician Elton John.
The couple are now known as the duke and duchess of Cambridge.
