Peter Bosz has signed a two-year deal to become Lyon's new head coach after the departure of Rudi Garcia.
Former Ajax and Borussia Dortmund coach Bosz was most recently with Bayer Leverkusen and will take the reins at Lyon on July 1.
The 57-year-old fills the void left following Garcia's decision to leave the Ligue 1 club this month, having guided them to fourth spot this season.
Bosz led Ajax to the Europa League final in 2017, beating his new employers in the semi-final, before a brief and disappointing spell with BVB.
He was sacked by Leverkusen in March and replaced on an interim basis by former Stuttgart boss Hannes Wolf, having endured a run of four wins in 18 matches in all competitions.
Lyon lost to Nice on the final day of the French season to miss out on Champions League qualification.
The club confirmed the appointment on their website, adding that club president Jean-Michel Aulas, football general manager Vincent Ponsot and sporting director Juninho would join Bosz in a news conference on Sunday.
Lyon said the quartet would "clarify the new parameters of the team's technical organisation and explain what they will expect from the entire first team, as this commencement of a new cycle will give an added dimension to Olympique Lyonnais' ambitious project, both domestically and in the Europa League".
