Lee Johnson has signed a four-year contract at Hibernian.
The former Sunderland and Bristol City manager was selected by the Scottish club after a vigourous search.
Hibernian's executive chairman Ronald J Gordon said. "There were a number of high-quality managers interested in the role and we analysed them all thoroughly.
"The candidates were interviewed in depth by a panel of directors before we unanimously came to the decision that Lee was the outstanding candidate and the perfect fit for us.
"Not only does Lee have great experience in management, but he also has knowledge of the Scottish and English game, will bring a definitive style of positive play to Hibs and has a proven record of success."
