Gary Kennedy has been appointed chair and non-executive director of Goodbody Stockbrokers.
It comes as the current chair, Dr Michael Somers, steps down after 11 years in the role.
Mr Kennedy will join the board and take up the position with immediate effect.
He is currently the chair of Greencore Group, non-executive chair of Norcros and non-executive director of Focus Ireland.
He was previously group director of finance & enterprise technology of AIB and a member of the AIB board.
Last September, AIB completed the purchase of Goodbody.
"We will really benefit from Gary’s wealth of experience and excellent track record which will be crucial as we look to significantly grow the business as part of AIB Group," said Martin Tormey, Goodbody Chief Executive.
"We have ambitious plans as we enter this new chapter of our company’s development and this appointment reflects that," he added.
Commenting on his appointment, Mr Kennedy said he is delighted to take on the role.
"I look forward to working with Martin and the team as the company embarks on its ambitious growth strategy to deliver significant shareholder value," he said in a statement.
"I believe the firm is well positioned to achieve its ambition by building on its core pillars of client focus, quality advice and trusted relationships," he added.
