The Worthington Cup will be called the Carling Cup from next season after the Football League agreed a three-year deal with brewers Coors.
Coors had sponsored the League Cup for the previous five years but have decided to switch the branding from Worthington to Carling after renewing the contract.
The League is still trying to recover financially after the collapse of ITV Digital and there had been fears that they might struggle to find a new sponsor for the Cup.
But the League's commercial director Richard Masters said there was plenty of interest in partnering the competition, which guarantees entry into the Uefa Cup.
"The level of interest shown in the sponsorship of the League Cup, in what it is widely perceived as a difficult market, has been extremely encouraging for the League and its clubs," said Masters.
"This competition has successfully demonstrated its enduring appeal over the
last few seasons, and it can only go from strength to strength in the future."
League chairman Sir Brian Mawhinney said he was delighted that Coors were on board after they had initially stalled on putting pen to paper.
"Over the past five seasons Coors Brewers have become highly valued partners
to the Football League," said Mawhinney.
"The healthy increase in revenue it delivers will provide a timely boost to our clubs as they begin their preparations for the new season and is a massive vote of confidence
in League football."
The draw for the first round of the Carling Cup will be made at 1000 BST on 25 June.
