The Party In The Park event will be held in Hexthorpe in August - and the team behind the project want it to become a celebration of Britain and British culture to tie in with national celebrations marking The Queen's birthday.
Stuart Boardman of organisers Hexthorpe Social Enterprise said: "We were using it celebrate the Queen's birthday, but we decided to broaden it out and have a party centred around Britain and all things British."
The group is now looking for community groups, organisations, stall holders and charities to take part in the event which will take place at Hexthorpe Flatts on August 27.
There will also be live music, games, food and dozens of other events at the party.
