The 18-year-old is believed to have been attacked at the campsite at Strathallan Castle estate in Perthshire, Scotland, on Thursday night.
Detectives have launched an investigation into the alleged rape - and have carried out forensic checks at the scene, the Daily Record reports.
News of the shocking attack follows the deaths of two teenagers which may be linked to drugs.
A Police Scotland spokesman said of the reported rape:”Police are making enquiries into a report of a rape of an 18-year-old female on Thursday evening.
It is believed the teenager was attacked following a night in the famous Slam Tent.
Around 80,000 people were at this year’s festival.
One fan said she saw police investigating at a tent on the campsite on Friday morning.
She said: "The police were focusing their attention on a specific area and this was on Friday morning.
“I was told there had been a report of a rape, but that was all.
,br /> “No one officially said anything, and it make my skin crawl to think that someone could have carried out this attack and then just carried on partying at the festival.”
