Thomas Tuchel will take over from the departing Jurgen Klopp at Borussia Dortmund, the Bundesliga club have confirmed.
Earlier this week, Klopp announced he would be leaving at the end of the season, bringing an end to a successful seven-year spell at the helm.
Like Klopp, Tuchel – who has agreed a three-year deal, which starts on July 1 – is a former Mainz coach, enjoying five years there before departing at the end of last season after a seventh-placed finish.
During his time at Signal Iduna Park, Klopp won two Bundesliga titles and the DFB-Pokal, as well as guiding the club to the UEFA Champions League final in 2013, where they lost to Bayern Munich.
This season, however, Dortmund have struggled in the league and looked like relegation candidates before a strong second half to the campaign saw them climb into the top half with five games still remaining.
Tuchel will be charged with returning Dortmund to the upper reaches of the division, but may take over a side who will not be in Europe next season.
The 41-year-old has no major honours to his name.
