Former Telstra chair Catherine Livingstone will takeover the chairmanship at Commonwealth Bank when David Turner retires.
Mr Turner, who has served as chair since 2010, announced on Wednesday he will retire at the end of 2016.
He said it had been a privilege to work on the board, supporting customers and fulfilling the bank's role in the wider economy since the global financial crisis.
"It has been exciting to be chairman of the bank in such a fast changing environment," Mr Turner said in a statement.
He said Ms Livingstone, who is currently a non-executive director at the bank, had good qualifications in technology and innovation after working as Telstra chair and chief executive of health technology firm Cochlear.
