Up to 800 athletes will travel through London on Monday, September 10, to celebrate the achievements of British Olympians and - hopefully - Paralympians.
A total of 21 floats will carry the athletes along the route, with medal winners spread out along the parade.
The event is called Our Greatest Team Parade and is organised by the Mayor of London and the British Olympic Association and the British Paralympic Association.
Sailor Ben Ainslie It will set off from Mansion House in the City of London, passing St Paul's Cathedral and into Trafalgar Square - where fans will be able to follow the whole parade on a big screen.
The final stretch up The Mall to Buckingham Palace is the only ticketed section - with spaces reserved for Olympic organisers, support teams for the athletes and a selection of children from London schools.
Prime Minister David Cameron will then honour the athletes with a special event to recognise their achievements - more details of this are expected to be released in the coming days.
Kayak champion Ed McKeever London Mayor Boris Johnson said: "In the ancient world, crowds would line the streets to welcome their triumphant Olympians home, where they would be ecstatically venerated and their victories chronicled for the ages."
Some will be disappointed that the event is being held on a Monday but organisers say it is to make sure the athletes are still in town after the Paralympic Games ends.
Employers are being encouraged to be lenient and allow people time off work if possible.
Team GB finished third in the medal table after winning 29 gold medals, 17 silvers and 19 bronzes - a total of 65.
