The ex Celtic boss and Leicester City player takes over at a side who have won just one league game so far this season.
Bolton Wanderers have appointed former Celtic boss Neil Lennon as their new manager, replacing Dougie Freedman who left the club earlier on in the month.
And late on Sunday night Bolton released pictures of the 43-year-old at the Macron Stadium.
"I've got a big job on my hands, but that's the challenge," Lennon told BBC Radio 5 live. "I'm very excited about that.

"My objective is to put right the results that have gone against us recently and get them playing a style of football that will please the Bolton fans.
"I've left one great club with a great history and I'm going to another club with a great history," he added.
Given that they are rooted to the bottom of the Championship at present, Bolton must surely be delighted to have brought in a manager of Neil Lennon's reputation and ability.
Though it is often difficult to judge the strength of manager's in Scotland that come from one of the two big Glasgow clubs, Celtic's struggles this season certainly indicate what the Northern Irishman brought to the Bhoys.
Three league title wins in a row, two Scottish cup wins and two seasons in the Champions League proper are just a few of Lennon's achievements in his maiden managerial job.
Given that a large portion of his playing career was spent south of the border, it was no surprise to see Lennon leave Celtic Park in order to try at his hand in England, and after being linked with several Premier League and top Championship clubs, he will now take over the task of attempting to fire Bolton back into the top flight after an absence of three seasons.
