The Imps have extended their partnership with Mundys Estate Agents.
The Lincoln-based firm will continue as silver partners for the 2021/22 campaign. As well as seeing their branding on the LED perimeter advertising boards, they also sponsor the club's Man of The Match polls on social media.
Imps director of commercial affairs Andrew Whitham said: "This is a continuation of a long-lasting partnership where both bring real value to each other.
"Both the club and Mundys can trace their roots in the city back to the Victorian period, and I'm particularly pleased to be working with such a well-established local company."
Mundys have supported the club for many years through sponsorship, and have backed the club's Man Of The Match since the 2018/19 season.
Simon Bentley, senior partner at Mundys Estate Agents, added: "As a local company we're pleased to be able to back the club, which is a key institution in the community.
"We're right behind the team and are sure they will again have a great season on the pitch."
