Per Kjeld Sørensen (born 18 December 1950) is a prominent Danish Tibetologist who specialises in Tibetan and Himalayan history, literature and culture.

As his principal student, Haarh had a lasting influence on Sørensen, particularly inspiring his interest in Tibetan history.

He was the recipient of an Alexander von Humboldt Stipend (1991–92) in Bonn, Germany, a sojourn that resulted in one of his most well known works, Tibetan Buddhist Historiography (1994).

In 2015 he was a participant in the Tibet Research Group on “Tibetan Genealogies" at the Berlin Institute for Advanced Study, with Guntram Harzod (head), Tsering Gyalpo (Lhasa) and Shen Weirong (Beijing).
