Cincinnati's Paul Brown Stadium is now Paycor Stadium.
The team signed a naming-rights deal with Cincinnati-based Paycor, a human resources company, on Tuesday.
Financial terms were not disclosed for the 16-year agreement.
The 65,515-seat stadium opened in 2020 and was originally named after franchise founder Paul Brown.
"This is a move that I think my father would have agreed to. He was always for what is best for the football team," Bengals president Mike Brown said in a statement. "This partnership allows the Bengals to continue to compete at the highest level in the NFL and exemplifies our long-term commitment to the community."
The defending AFC champion Bengals open the preseason Friday at Paycor Stadium against the Arizona Cardinals. Cincinnati's regular season home opener is Sept. 11 against the Pittsburgh Steelers.
