Butlers bar, at Kirkstall Forge, will also be open from 4pm.
Lucinda Yeadon, community liaison manager at CEG, said: "We hope as many people as possible are able to come along to Kirkstall Forge, enjoy music from live bands, sample Ukrainian fayre and help raise much-needed funds to support refugees.
“I would like to thank Leeds Rhinos and other businesses which have kindly offered some great prizes for our auction.
“Any businesses wanting to donate, please get in touch.
“Everyone who comes along to the event will also be given free sunflower seeds to plant in solidarity and support for Ukraine.”
Coun James Lewis said: “The way that residents in Leeds have responded to the crisis in Ukraine has been truly inspiring.
“We have seen many, many examples of people doing their bit to help those in need, not least by making donations to the council’s Leeds Together For Ukraine fundraising appeal.
“The support already being shown for the Kirkstall Forge event is further testament to our city’s generous nature, and hopefully it will raise a significant amount for a very deserving cause.”
