Flick signed a three-year contract effective from July 1 to succeed his former boss, who is ending his 15-year tenure after the tournament, the German soccer federation said Tuesday.
Flick’s last game in charge of Bayern Munich was on Saturday.
Flick was Löw’s assistant from 2006-14, when they helped Germany win the World Cup in Brazil. He left to become the federation’s sporting director through 2017, and then took over at Hoffenheim.
The 56-year-old Flick most recently led Bayern to two Bundesliga titles, a Champions League victory and German Cup success. He informed the Bavarian club in April that he wished to leave.
