Per Karl Hjalmar Dusén (1855-1926) was a Swedish civil engineer, botanist and explorer. As a botanist his interests included pteridology, bryology and paleobotany. He made botanical expeditions to Africa, Greenland and South America.

Between 1890 and 1892, Dusén collected nearly 560 leaf fossils preserved in basalt in the vicinity of Mount Cameroon on the west coast of Cameroon. Later, these fossils were studied by the German paleobotanist Paul J. Menzel (1864-1927).

His botanical specimens are at the New York Botanical Garden, being obtained when they acquired the herbarium of Princeton University in 1945.
