Former Celtic Football Club chief executive Peter Lawwell is returning as non-executive chair, just 18 months after leaving.
He will replace Ian Bankier on 1 January, having previously served for almost 18 years, prior to his retirement in the summer of 2021.
During his tenure as chief executive, the club won 29 trophies, including 13 league titles and an unprecedented 'quadruple treble'.
Lawwell commented: "As a lifelong Celtic supporter it is a great privilege to be asked to take up the position of chairman, having already been part of our great club for nearly 18 years.
"I will be offering my support and guidance to the board and executive management team to ensure that we continue to drive the club forward and protect and promote the interests of our supporters."
Celtic's chief executive Michael Nicholson said: "Peter has a wealth of experience in the football industry at a domestic, European and global level, which is invaluable to the club going forward.
"Our collective objective is to create a world class football club that our supporters can be proud of, competing at the highest level, with a strategy based on growth and continuous improvement."
"On behalf of the board, and all of our colleagues at the club, I thank Ian Bankier for his service and contribution, and wish him and his family the best for the future."
Bankier said: "Peter will be a most effective sounding board for the executive and a fine representative both domestically and abroad.
"I would like to thank everyone at Celtic for their support during my term of office; I shall miss them all."
Celtic manager Ange Postecoglou added: "It is fantastic news for the club that Peter will be taking up the role of chairman.
"He was instrumental in bringing me to Celtic, I know the love he has for the club and I know that his wealth of experience and knowledge will be invaluable to us all as we move forward together."
Lawwell’s son Mark is Celtic's current head of first team scouting and recruitment.
