The British schoolgirl, who was born with learning difficulties, was reported missing from her family's holiday resort in Malaysia more than a week ago.
Police announced this morning that the body of a white female was found in the forest surrounding the resort.
A police spokesman told reporters earlier today: "Just now the body was taken by helicopter to hospital.
"Our team here has engaged the family and told them about the news and we are going to the mortuary and the hospital to identify the body."
The spokesman could not confirm whether there were visible injuries to the body found, but said a post-mortem examination would take place soon.
The Lucie Blackman Trust, which is handling media for the Quoirin family, confirmed "with great sadness that the body found today is that of missing teenager Nora Quoirin. Local police have confirmed identification".
The trust added that the teenager's family would not immediately be making any statement, and asked that their privacy be respected "at this awful time".
The discovery follows an intensive search by more than 300 people and international police teams.
The schoolgirl from London was first reported missing from her family's holiday resort near Seremban, Malaysia last Sunday.
Her father raised the alarm after discovering that Nora was not in her bedroom when the family woke up.
Her family maintained throughout the search she had been abducted, saying it was out of character for her to wander off.
Speaking on Sunday, Nora's mother, Maebh, spoke of her gratitude to the rescuers.
She said: "We see you working so hard and also praying with us and being with us."
A fundraising page set up by members of her extended family raised more than £100,000 in an effort the find the teenager.
The fundraiser came as an emergency hotline was set up to gather intelligence on the whereabouts of Nora.
A week after her disappearance, the National Crime Agency and the Metropolitan Police joined search teams in Malaysia to find the teenager.
A local shaman, regarded as spiritual figures by some, also helped with the search to find Nora.
