Tim Clancy has brought an end to his time at Cork City manager after Friday night's 2-1 home defeat to Derry City.
The former Drogheda United and St Patrick's Athletic boss had guided Cork to automatic promotion from the SSE Airtricity Men's First Division last year.
But this season in the Premier Division has proven to be difficult, with the club second from bottom and occupying the relegation play-off spot and eight points adrift of definite safety after 15 rounds of action.
"The decision to leave is mine and mine alone," said Clancy of his decision to depart Turner's Cross after 18 months in charge.
"I am proud to have brought this team back to the League of Ireland Premier Division, and believe they have so much more to give. I would like to thank the players, Dermot Usher and the entire staff at Cork City FC for the opportunity to work with them, and wish them the best for the remainder of the season."
Cork City owner Dermot Usher expressed disappointment that the Meath man is leaving the role but accepted the decision, with the club getting the recruitment process underway to find Clancy's successor.
"I spoke with Tim this evening, and while obviously disappointed, I fully respect his decision," he said.
"On behalf of the club, I would like to thank him for his commitment over the past 18 months, and for everything he has done for the Rebel Army."
