The former South Africa seamer spent two years as assistant coach to Matt Walker, whose side reached the One-Day Cup final last season
Kent have confirmed that assistant coach Allan Donald will leave at the end of the season after two years at the club.
The 52-year-old started work in Canterbury at the start of 2018 and will now depart at the conclusion of the current campaign.
Alongside head coach Matt Walker, the former South Africa bowler helped Kent reach the One-Day Cup final and win promotion from County Championship Division Two.
“It’s been a great experience working with Walks and the whole squad at Kent," the recent ICC Hall of Fame inductee said.

"Over the past two seasons, it’s been hugely rewarding to see the development of young and exciting players.
"We have been uncompromising in raising standards here through our transition into Division One and shown that we can compete and win at this level.
"There’s a squad of players here who are hungry to learn and it has been great to be a part of the team that has set up a culture and values that will stand Kent in good stead for the future."

Kent, who are second in the T20 Blast South Group and on course to stay up in Division One, are set to embark on a major restructuring behind the scenes in the wake of Donald's exit.
That overhaul will include the appointment of a full-time bowling and batting coaches who are able to work with the squad throughout the year.
Director of cricket Paul Downton added: "It will be a major boost to our strategic goal of producing more home-grown Kent cricketers in the future, and to help them in their transition from county age groups and the Kent Cricket Academy to the first team."
