Pizza, pies, doughnuts and cakes are just some of the vegan treats that will be on offer in Market Square on Sunday, September 8.
Ethical jewellery, accessories and artwork will also be on offer from dozens of independent traders.
Jennie Sim, who runs Vegan Knights Events, said: “Chestefield is first and foremost a market town and this is a great way to celebrate that along with the fact that veganism is bigger than ever.
“This is because people are realising that veganism not only benefits animals but the environment. Even David Attenborough is a vegan now.
“Events like these support local businesses, fight misconceptions and bring vegan options, of which there are more than ever available now, to the table.”
The event starts at 10am and, while stocks last, will run to around 4pm.
