The former Celtic boss has linked up with Hibs
The 44-year-old succeeds Alan Stubbs, who left to join Rotherham last week after winning the Scottish Cup last month.
Lennon’s long-time assistant Garry Parker will join the former Celtic and Bolton boss at Easter Road.
Hibs chairman Rod Petrie told the club’s official site: “We are delighted to have secured a head coach of Neil’s calibre and profile, and we look forward to him bringing his drive and mentality to our campaign to win the Championship this season and secure promotion back to the top flight of Scottish football.”
Leeann Dempster, the club’s chief executive, added: “As soon as Neil was identified as the outstanding candidate we were determined to bring him to Easter Road. He has managed at a very high level, taking Celtic to the last 16 of the Champions League, and we were attracted by his ability to get the most out of players and his driven, winning mentality.
“On behalf of everyone at Hibernian FC, we would like to extend a warm welcome to both Neil and Garry.”
