Ove Vilhelm Paulsen (22 March 1874 – 29 April 1947) was a Danish botanist. He studied at the University of Copenhagen under professor Eugen Warming. He was a keeper at the Botanical Museum of the University of Copenhagen from 1905 to 1920, when he became professor of botany at the Pharmaceutical College in Copenhagen, a position he held until 1947. He studied the flora of Denmark, plankton of the North Atlantic and the flora of Central Asia. He went on expeditions to Northern Persia and Pamir as early as 1898-1899. During his travels through Pamir, he was accompanied by the Danish explorer Ole Olufsen. Ove Paulsen visited North America with the second International Phytogeographic Excursion and subsequently described the biome zonation from east to west in a paper.
The plant species Kali paulsenii is among the many plant taxa named for him.
