An afternoon of live music, entertainment, lantern making and a lantern procession will culminate on Mikey North, who plays Gary Windass in Coronation Street, turning the lights on at 4.30pm.
On the stage will be singers Beverley, Stuart James, Shaun Langford, Dayton Grey and other entertainers while street acts will be performing throughout the crowd.
Wednesbury North Councillor Luke Giles is looking forward to seeing months of organisation come to fruition.
He said: “I’m really excited and proud of how the community have come together. All the artists are performing for free and have given up their own time which shows once again Wednesbury comes together for Christmas.
“The events team have organised this alongside myself as town lead and I would just like to thank them for their hard work.”
He said: “We have got so much entertainment on the day. We have two stages with singers and performers all afternoon.
The grand opening is at 1pm followed by entertainment on the stage.
Lantern making will begin in Market Place between 1.30pm and 3.30pm with the lantern procession between 3.30pm and 4pm.
