The group called Vegan Lincs aims to educate people about the benefits of a healthy vegan lifestyle, raise funds for local animal charities and provide information to the catering industry on dietary requirements of vegans.
The group will also organise social events for members and supporters and help promote local and national vegan-friendly businesses.
Vegan Lincs will be officially launched at The Healthy Hub in Beaumont Fee on Saturday, July 11.
There will be free vegan food tasting as well as a stall by The Vegan Society and a raffle to raise funds for local animal charities.
Group Co-ordinator Linda Wardale said: "I have had the idea for a while and voiced my thoughts to a few vegan friends recently.
"Their comments and interest inspired me to take things further.
"We have the full backing of the Vegan Society and everyone is really excited, enthusiastic and supportive."
