Eugene J. Sheehy is Group Chief Executive of Allied Irish Bank Plc. He was educated at Salesian College, Limerick.

He joined AIB in 1971 when he was 17 years old and spent 20 years in retail banking, including branch manager appointments in a number of Dublin branches at Capel Street, Dame Street and Phibsborough.

He executed a radical overhaul of AIB's branch banking operation in 1992 which entailed new and, in the view of many, unpopular changes to work practice. He also brokered a deal with staff to secure implementation. He was appointed General Manager, Retail Operations in 1999, and Managing Director, AIB Bank (Republic of Ireland) in 2001. He was appointed Chief Executive Officer of AIB's USA Division and six weeks later Executive Chairman-Designate of Allfirst Financial Inc in March 2002 when it was in melt-down following the activities of John Rusnak.

Sheehy was appointed Chairman and CEO, Mid Atlantic Division, M&T Bank, and to the Executive Management Committee and Board of M&T in April 2003, following the merger of Allfirst and M&T. Appointed AIB Group Chief Executive-Designate in March 2005, co-opted to the Board May 12, 2005, and assumed responsibility as Group Chief Executive with effect from July 1, 2005.
