"This new sponsorship is a fantastic partnership for both companies and also for Grimsby itself. We are delighted that a company as prestigious as Young's is willing to increase its local ties by supporting Grimsby Town in this way," chairman Peter Furneaux.
"Since Young's is one of the biggest employers in the Grimsby area, this deal will add the strong relationship that the football club already has with the community."
The deal will see both Youngs and Nike on Town's shirts for the next two years.
