Jeffrey Immelt (born February 19, 1956, Cincinnati, OH) is the current chairman of the board and chief executive officer of the U.S. based conglomerate General Electric. He was selected by GE's Board of Directors in 2000 to replace John Francis Welch Jr. (Jack Welch) following his retirement. Previously, Immelt had headed up GE's Medical Systems division (now known as GE Healthcare) as its President and CEO.

Immelt holds an A.B. in Applied Mathematics from Dartmouth College where he currently serves on the board of trustees and was president of his fraternity, Phi Delta Alpha, and an M.B.A. from Harvard Business School. He has been with GE since 1982 and is on the board of two non-profit organizations, one of which is the Robin Hood Foundation, a charitable organization which attempts to allieviate problems caused by poverty in New York City.

His tenure as Chairman and CEO started off on a low note - he took over the role on September 7, 2001 - just four days before the terrorist attacks on the United States, which killed two employees and cost GE's insurance business $600 million, as well as having an obvious direct effect on the company's Aircraft Engines sector.
