Ludwig Eduard Theodor Lösener (23 November 1865 – 2 June 1941) was a German botanist who collected widely in the field in Germany: Amrum island (1912), the Alps, the Black Forest, Bavaria, Rügen island and Tyrol in modern Austria. His speciality was the Aquifoliaceae of the world. He also studied cultivars of Ilex species. His name is usually spelled as 'Loesener' in English sources.

In 1941, botanist Albert Charles Smith published the genus Loeseneriella, in the family Celastraceae, in his honour.[1]
