Burnley chief executive David Baldwin will leave the club in June 2020 to take up the same role at the English Football League.
Baldwin leaves Burnley after four years, during which time the Clarets won the Championship title and qualified for the Europa League.
"I have thoroughly enjoyed my spell at Burnley," Baldwin said.
"I feel now is the right move for me at this point in my life and I'm looking forward to a new challenge."
Burnley chairman Mike Garlick, who will act as temporary chief executive until a replacement is appointed, said Baldwin had been a "superb appointment" who "helped move the club forward".
