The Football Conference has ended its sponsorship deal with Nationwide and will switch to online betting firm Blue Square for next season.
A three-year deal has been signed with the new sponsors which will see the end of the Conference's nine-year association with Nationwide.
The Conference will now be known as Blue Square Premier.
The Conference North and South are to be renamed Blue Square Northern and Blue Square Southern respectively.
Football Conference chairman Bill King said: "Our league is the gateway to the clubs in the professional structure in the UK and is an established part of the UK football scene.
"I'm delighted to be seeing a piece of non-league football history in the
making and am extremely excited about what this partnership with Blue Square can achieve."
