The Wave on the Walls was organised as part of the 400th anniversary celebrations of the well known landmark, as well as to raise funds for the Foyle Hospice.
Volunteers young and old wore their specially designed red T-Shirts as they took part in the historic human chain on Sunday morning.
Among those participating in the event was Deputy First Minister Martin McGuinness, who said it was great to celebrate the history of the famous walls.
He added: "The Walls belong to everybody now, and to have so many people here today to appreciate the history and to appreciate the forward development of this city is really powerful."
Also taking part in the Mexican wave was Derry City Mayor Councillor Martin Reilly.
He said: "It is great to see so many people to come out to celebrate the walls but it is also for a good cause as well."
Derry Walls Day 2013 will mark the commencement of Walls400, the programme of activities taking place during 2013 to 2018 to celebrate the quatercentenary of the building of Derry's City Walls.
Commenting on the number of people who took part in the event, Mark Lusby from the City Walls Heritage Project said: "I am absolutely relieved, delighted and proud of the people of Derry and the surrounding areas for turning out in force for us."
