Lighting the Flame 2010 will take place between 10am and 2pm and is part of the national 2012 Open Weekend, which aims to mark the fact there are just two years to go until the London Olympics.
The council said the event would be an opportunity for residents to meet local clubs and find out what they can offer. As part of the day there will be hockey, football, rugby, tennis and dance demonstrations.
Other planned activities include sumo-suit wrestling, a track and field event and performance arts. There will also be a children's fun fair and arts and crafts.
Organisers are also hoping visitors will be attracted by Dragon Boat racing at nearby Lakeside which will see 20 teams fighting for a place on the winners' podium.
Doncaster Tourism, the council's tourism team, is putting on the race along with Doncaster St George's Rotary Club and the aim is to raise funds for Macmillan Cancer Support and other charities.
Racing will take place between 11am and 4.30pm and will start and finish with a performance by "dragon dancers". To celebrate the event, The Lakeside Village shopping outlet is also holding a Chinese-themed family fun day.
Peter Davies, the Mayor of Doncaster, will be presenting prizes for Dragon Boat racing. He said: "Lighting the Flame is all about showcasing all the hard work and commitment our local grass roots clubs put into the sporting life of the borough.
"I would encourage everyone to come down and see if there is a club for them."
