Ernst Vilhelm Østrup (21 September 1845, in Roskilde – 16 April 1917, in Frederiksberg) was a Danish botanist and phycologist, mainly working on diatoms.

In 1873 he received his cand. polyt. degree, and later worked as a schoolteacher in Copenhagen. His diatom research largely dealt with species found in Denmark, Greenland, Iceland, Faeroe Islands and Jan Mayen.[1]

The diatom genus Oestrupia (Heiden)[2] and the species Diploneis oestrupii (Hust.), Surirella oestrupii (Gran) and Navicula oestrupii (Cleve) are all named in his honour.
