Giacomo Giuseppe Federico Delpino (27 December 1833 – 14 May 1905) was an Italian botanist who made early observations on floral biology, particularly the pollination of flowers by insects.

He wrote Pensieri sulla Biologia Vegetale (Thoughts on Plant Biology) in 1867 and this failed to gather sufficient notice due to it being written in Italian.

"[1] Delpino's early studies after high school were in mathematics and natural sciences at Genoa but he had to drop out in 1850 upon his father's death.

Economic worries forced him to seek work and he became an official in the Customs House of Chiavari and later made botanical trips to Constantinople and Odessa.

He moved in 1867 to Florence to assist Filippo Parlatore, In 1871 he was appointed as professor of natural history at the Forestry School in the Royal Institute of Vallombrosa.

Delpino wished to travel around the world and boarded the warship Garibaldi as a naturalist with the Prince Tommaso di Savoia.

[7] In his Handbuch der Blütenbiologie (1898–1904), Paul Knuth, considered Delpino as one of the four pillars of support for Darwin's work on plant pollination.

[1][8] In 1891, botanist Carl Ernst Otto Kuntze circumscribed Delpinoina, which is a genus of fungi within the Ascodichaenaceae family and named in Federico Delpino's honour.
