It is the first time that the ground has been renamed for a sponsor.
Dale, who bought the stadium outright earlier this year, groundshare with rugby league side Rochdale Hornets.
"Today is a landmark day for Rochdale and one which at times over the past 10 years I could only ever dream would happen," said chairman Chris Dunphy.
"The board of directors and I were unanimous in our decision, which we believe will bolster our future sustainability and are extremely proud to announce them as our major commercial partner."
League One side Rochdale have renamed their Spotland ground to the Crown Oil Arena after agreeing a six-figure five-year sponsorship deal.
