Chris Caisley has been in charge of the Super League Champions for 16-years but will leave the board in February.
He said: “I firmly believe that the time is right for us to close this particular chapter in the club's history and move forward positively into the second decade of Super League.
“I have been chairman since 1989 and 16 years is a long time, but it is the right time to stand down for many different reasons.”
The chairman of rugby league champions Bradford has confirmed he is to stand down next year.
