Dean Smith becomes 9th Championship manager sacked this season
Dean Smith has been sacked as Norwich City head coach just over a year after taking charge following a run of just three wins in 13 Championship matches.
Assistant manager Craig Shakespeare and first-team coach Liam Bramley have also left Carrow Road.
Steve Weaver and Allan Russell have taken caretaker charge of the team.
"As the club continues to work towards its on-field objectives this season, the board believe that it is the right time to make this transition," Norwich said in a statement.
"The club will now work to identify and appoint a new head coach that is able to deliver both the level of performances required to challenge at the top end of the league whilst implementing a consistent style of play."
Smith publicly questioned the attitude of some fans after the home defeat by Blackburn on 17 December and said playing away was better for his side.
"I think a lot of them have been waiting for this period to happen, or wanting it to - I don't know," he told BBC Radio Norfolk at the time.
Canaries sporting director Stuart Webber added: "This was a tough decision, but one that we felt was necessary to give ourselves the best possible chance of achieving our objective of promotion to the Premier League this season.
"With just under half of the season remaining and three consecutive home games on the horizon we now have a real opportunity to build some forward and positive momentum, both on and off the pitch."
