Barnsley and CK Beckett have signed a new home and away shirt deal until the end of the 2016/17 season, with the company also renewing it's sponsorship of the South Stand at Oakwell.
CK Beckett will also become the new sponsors of the Family Area in the East Stand and, as part of the deal, 150 complimentary tickets will be offered to Barnsley schoolchildren every week.
"Barnsley Football Club have enjoyed a special relationship with CK Beckett for more than six years now," Barnsley chief executive Ben Mansford told the club's official website.
"We've developed a truly great partnership and we're thrilled to have a local company as our principal sponsors.
"This partnership continues to deliver for both the business, the club, our supporters and the next generation of Barnsley fans."
Barnsley suffered the heartache of relegation from the Championship last season, but are tipped to make an immediate return to the second tier.
