The parade to celebrate the success of Team GB's Olympic and Paralympic athletes will take place in Manchester on October 17.
The Prime Minister Theresa May said it will be a celebration fit for heroes.
Final details are now being worked out - there will also be an event in London on the following day.
Manchester, the home of British Cycling and taekwondo and the ParalympicsGB swimming team, is the ideal place to hold a national parade, according to Manchester City Council deputy leader Sue Murphy.
Britain confirmed its place as a sporting powerhouse by coming second in both the Olympic and Paralympic medal tables.
Olympic cycling's golden couple Jason Kenny and Laura Trott, runner Mo Farah, and swimmer Adam Peaty, plus Paralympic champions Dame Sarah Storey, Kadeena Cox, Jonnie Peacock, Lee Pearson and Will Bayley are among the sporting heroes from Rio 2016.
Britain's Olympic athletes won 27 golds from 15 sports, and 67 medals in total, smashing UK Sport's pre-Games target of at least 48 medals, meaning Rio was the nation's most successful "away" Games.
ParalympicsGB won 64 golds, the most by a British team since 1988, and a total of 147 medals.
Meanwhile nation's most successful female Paralympian Dame Sarah Storey returns to the UK later with the rest of the British team.
The cyclist from Stockport won three gold medals in Rio....bringing her career total to 14 golds in 7 games.
