Friedrich Wilhelm Ludwig Kraenzlin (aka Kränzlin; 25 July 1847 – 9 March 1934) was a botanist associated with the Natural History Museum (BM).^[1]

In the history of the European study of South African orchids, Friedrich "Fritz" Kraenzlin (Kränzlin) appears after Heinrich Gustav Reichenbach describing many new orchids in the region, and revising some of the genera. His book Orchidacearum Genera et Species was never finished, but the volume containing the Habenaria, Disa, and Disperis genus was completed in 1901.^[2]
