Cardiff City FC has appointed ex-Millwall player and manager Neil Harris as the club's new first team manager.
Warnock oversaw 144 matches and famously led Cardiff to promotion at the end of the 2017/18 season.
Warnock's assistant manager Kevin Blackwell and Ronnie Jepson will also leave the club.
Harris will oversee training at the Vale Resort on Monday ahead of his first City match away to Charlton Athletic on Saturday 23rd November.
David Livermore will replace Blackwell as assistant manager, while James Rowberry and Andy Dibble take on first team coach and goalkeeping coach respectively.
Owner Tan Sri Vincent Tan said he has "full confidence" in Neil to bring the club success.
"I am glad to offer him this opportunity and look forward to seeing what he is capable of achieving with Cardiff City.”
Chairman Mehmet Dalman said, “Neil is a passionate manager who has all of the right attributes to take the helm at Cardiff City.
"I know he’s eager to get to work and we look forward to seeing him strive to get the best out of our tight-knit and talented group of players."
