Liam Manning had been in charge at Bristol City since November 2023 and led the Robins to the 2024-25 season's play-offs, only to lose 6-0 on aggregate to Sheffield United in the semi-finals.
His appointment at Carrow Road was confirmed last week.
He replaces Johannes Hoff Thorup, who was sacked by Norwich on 22 April with the team 14th in the Championship following a run of six defeats in eight games.
In November, the Canaries set a target of getting back to the Premier League within 3-5 years.
