Organised by the Royal Commonwealth society, the ceremony is the centrepiece of celebrations across the Commonwealth.
The Duchess of Cambridge, whose second child is due to be born in April, chatted with dignitaries and members of the Commonwealth nations before walking into the ceremony at the Abbey in a procession with the other royals.
A line of flag-bearers, each carrying the flag of a different member of the commonwealth, led the Royal family out of the Abbey, where outside, the queen received a bouquet of flowers and spoke with choristers.
Commonwealth day is celebrated on the second Monday in March every year. The day is a celebration of all of the Commonwealth nations and designed to encourage greater collaboration and co-operation between its members.
