The discovery was made on Sunday, after police were advised that a tent had been found at a secluded area of Torvean Quarry.
Within the tent police discovered human remains which appear to have been there for several months or longer.
The identity, age and sex of the deceased person are unknown.
A Police Scotland spokesman said: “It is not known how the person died, a post mortem will be held and the death is being treated as unexplained.
“The tent was in a secluded area of the quarry and was a distance away from paths used by the public.
“It appears that the person had been living in this tent for a period of time and it is likely he or she would have been seen by people nearby.”
Police are appealing for anybody who may have seen this tent or occupant, or that has any information that will assist in identifying the person concerned to contact Inverness Police on 101 or alternatively Crimestoppers on 0800 555111
