Arsenal are without a win in their last seven matches following Thursday’s 2-1 defeat to Eintracht Frankfurt in the Europa League.
The Gunners have won only four of their 13 Premier League games this season and are now eighth, eight points adrift of the Champions League places.
Emery was appointed head coach at Arsenal in 2018 on a two-year deal, succeeding Arsene Wenger after his 22 years in charge of the club.
However, the Spaniard has been sacked after just 18 months in the role “due to results and performances not being at the level required”, according to a club statement.
Freddie Ljungberg, former Arsenal midfielder and member of ‘The Invincibles’, will take charge of the first team while the club searches for a permanent replacement for Emery.
Arsenal director Josh Kroenke said: “Our most sincere thanks go to Unai and his colleagues who were unrelenting in their efforts to get the club back to competing at the level we all expect and demand.
“We wish Unai and his team nothing but future success.”
Arsenal say they have “full confidence” in Ljungberg, who will take charge of the Gunners for the first time against Norwich on Sunday, live on Sky Sports Premier League.
Sky Sports News understands several senior figures at the club, including head of football Raul Sanllehi and technical director Edu, had decided before the Frankfurt match that Emery needed to be replaced.
