Sinisa Mihajlovic has been sacked by Torino after Wednesday's Coppa Italia loss to rivals Juventus compounded a poor run of league form.
Torino had won just one of their last eight Serie A matches, leaving them 10th in the table, before succumbing 2-0 to Juve.
Former Fiorentina, Sampdoria and AC Milan coach Mihajlovic took charge in May 2016 and led Torino to a ninth-place finish last season.
Torino thank Mihajlovic for commitment
"The Torino Football Club announces that it has relieved Sinisa Mihajlovic from the position of coach of the first team," a statement on the Torino website read.
"Sinisa and his staff are thanked for the commitment and the passion shown in these 18 months in maroon."
Torino host Bologna when Serie A resumes after the mid-season break this weekend.
