Mackay's last game was against St Johnstone in Perth
Ross County have parted company with manager Malky Mackay.
Mackay joined the club in the summer of 2021 and led the team to a top-six finish in his first season.
He saved County from relegation at the end of last season with a dramatic penalty shoot-out play-off win against Partick Thistle in Dingwall.
But, after a meeting between Mackay, chairman Roy MacGregor and CEO Steven Ferguson, the club have decided a change is now required.
The Staggies have gone nine games without a win.
"Malky has brought so much more to the club and the wider staff than just football management," said MacGregor.
"The board would like to put on record our thanks for his contribution over the last two-and-a-half years and wish him all the best in the next chapter of his career."
Mackay's appointment in Dingwall was his first full-time managerial role since being sacked by Wigan Athletic seven years ago.
The former Celtic centre-back succeeded John Hughes, who replaced Stuart Kettlewell at County in December 2020 and left after keeping the club in the top flight.
The ex-Watford and Cardiff boss ended a four-year stint as Scottish FA performance director in November 2020.
