Police have confirmed they are investigating reports of an attack on Thursday evening.
The rape of a teenager at the T in the Park campsite is being investigated by police.
An 18-year-old girl was attacked at the festival in Perthshire on Thursday night.
A Police Scotland spokesman said: "Police are making inquiries into a report of a rape of an 18-year-old female on Thursday evening.
"Our inquiries are ongoing."
The deaths of a teenage boy and girl, both 17, in unconnected incidents, are also being investigated by police.
Peter MacCallum, from Lochgilphead, Argyll, and Megan Bell, from the north of England, were found dead at the music festival on Friday before the main arena opened.
Police have said the deaths of the teenagers may be linked to drugs.
T in the Park is Scotland's biggest music festival, regularly attracting more than 80,000 revellers over the weekend.
So far there have been 40 arrests at this year's event and more than 300 crimes, including the theft of a cash machine from the main arena in the early hours of Friday.
This year's event was the second to take place at the Strathallan Estate.
