The event, organised by sisters Aoife Dyson and Tara Howard, sees dozens of people get together at Holy Rood Parish Hall, on George Street.
It is made possible by support from an array of local community groups and businesses, including mental health support group and Proud of Barnsley nominee Project 14, which has donated £500 to putting the event on.
Thomas Armitage from Project14 said: “We’re delighted to contribute and support Aoife and Tara.
“Having volunteered for the last couple of years I have seen first hand what an amazing impact this event has on some of the most vulnerable in our society.
“I’m sure the lasses will put on another amazing event this year.”
Aoife, 32, of Park Road, Barnsley, said: “For the last two years we have partnered with Project 14 and this year we have received a significant contribution from them and without this we would have struggled to get the event up and running.
“There’s been an unbelievable amount of support from local businesses and we just want to say a massive thank you for making Christmas special for people in our community.”
Catering will be provided by Dodworth Deli and Cafe, and local musicians will perform through the day.
n The Barnsley Festive Feast will take place between 1pm and 4pm at Holy Rood Parish Hall on Saturday, December 21.
