Ian Bankier (right) was praised for bringing "great counsel and stability" to Celtic
Ian Bankier is to retire as Celtic chairman on 1 January.
The 70-year-old, who is also executive chairman of Glenkeir Whiskies Ltd, joined the board in the summer of 2011 and became chairman later that year.
Principal shareholder Dermot Desmond told Celtic's website: "We will ensure that we work very closely with Ian over the next few months to deliver a smooth and effective transition prior to announcing his successor."
He also praised Bankier's contribution.
"Ian has provided great counsel and stability across a sustained period of growth and success for the club," Desmond said.
Bankier said it had "been an honour and a privilege to serve the club I will always love".
"Our aim was always to deliver success on and off the pitch and, above all, to give Celtic fans a club they could be proud of," he added.
