Philip Henry Kuenen (22 July 1902, in Dundee – 17 December 1976, in Leiden) was a Dutch geologist.
In 1929-1930 Kuenen participated in the Snellius expedition to the seas surrounding the Sunda Islands of the Dutch East Indies.
Because the Dutch government had decided that geology would not be a major subject at Groningen University, Kuenen was able to dedicate most of his time to research.
Only in 1946 he became a full professor, during the German occupation in World War II the Nazis had prevented this because he had British ancestors.
Some of his other contributions to geology were geochemical calculations about sediments and the water cycle and research on absolute and relative sea level changes, the rounding of sediment particles, normal faulting in the continental slope domain and especially turbidites and turbidity currents.
