Police were called to the promenade below Wellington Crescent at Ramsgate on Tuesday where a 45-year-old man was found dead.
Witnesses saw the man fall from the top of the cliff. Officers cordoned off the area while an investigation was carried out.
The death is not being treated as suspicious.
Next of kin have been notified, but a formal identification will not be conducted until after the post mortem on Friday. It is believed the man lived in the Thanet area.
The tragedy happened at about 3.30pm on Tuesday. The matter has now been handed over to the coroner’s office.
