West Park will host the event - now in its fifth year - with youngsters sure to be entertained by special guests including Peppa Pig, the stars of In the Night Garden and Toy Story, Fireman Sam, Hello Kitty and Mickey and Minnie Mouse.
Signal 107 will broadcast live throughout the day while the city's branch of the Parachute Regiment will have a fleet of Second World War military vehicles on display, with veterans from key battles on hand to share their experiences.
This year's event will also give visitors the chance to try their hand at dozens of sports and sign up to free sports sessions thanks to Black Country Sportivate, while Light House Media Centre will provide a line up of show stopping local acts including headliner Beth Sherburn who will perform Joker, the new single she recorded with rapper Lil Wayne.
Cash raised from charity raffles will go to Wolverhampton Multiple Sclerosis Therapy Centre and the Parachute Regiment.
PC Joe Trusselle, from Wolverhampton Police, said: "Last year's event was a real success - we had more than 2,500 visitors and raised £1,500 for local charities.
"With pony rides, a climbing wall, inflatable assault course and more, this year's event is set to be bigger and better than last year and we hope to raise even more cash for local good causes."
Councillor Elias Mattu, Wolverhampton City Council's Cabinet Member for Leisure and Communities, added: "This is a great community event. It promises something for all the family and is a wonderful way to spend time in West Park."
The Family Fun Day takes place between 10am and 6pm and entry is free.
