Norwich appoint former West Brom, Sheffield Weds and Preston Boss as first team coach
The 57-year-old, who has also managed Sheffield Wednesday and Preston, joins the Canaries after a spell as Blackburn Rovers' assistant manager last season.
The Scot arrives after first-team coach Gary Holt left on 28 June by mutual consent, to seek a managerial role.
"Alan has worked with top managers. He brings a wealth of experience," manager Alex Neil told Norwich's club website.
The departed Holt had two separate spells on the coaching staff at Norwich. The 43-year-old ex-Scotland and Canaries midfielder had returned to Carrow Road in 2014 after leaving his role as Falkirk boss to coach under Neil Adams.
He continued the role when Alex Neil took charge in January 2015, and has seen them promoted to and relegated from the top flight in 12 months.
Holt now intends to seek a head coach or managerial role.
Irvine has always been regarded as one of the best coaches in the game and had a succesful spell as David Moyes right hand man at Everton - but his managerial spells at Preston, Sheffield Weds and West Brom have proved less fruitful.
