Alexei Pavlovich Fedchenko (Russian: Алексей Павлович Федченко; 7 February 1844 – 15 September 1873) was a Russian naturalist and explorer well known for his travels in central Asia. Alternative transliterations of his name, used in languages such as German, include "Aleksei Pavlovich Fedtschenko" and "Alexei Pawlowitsch Fedtschenko".
In 1868, he and Olga travelled through Turkestan, Samarkand, Panjkent and the upper Zarafshan River valley. In 1870, they explored the Fan Mountains south of the Zarafshan. In 1871, they reached the Alay Valley at Daroot-Korgan and saw the northern Pamir Mountains but was unable to penetrate southward.
He also collected significant numbers of insects from three explorations from 1869 to 1873. These were then studied by Ferdinand Morawitz in St Petersburg. He recorded 438 species belonging to 36 genera from Central Asia. 68 species of Andrena, 17 species from Europe and 51 new species.
Soon after their return to Europe, he perished on Mont Blanc while engaged in a tour in France. He had been trying to look at glaciers in France to see how they compared with those in Turkestan. His wife had him buried in Chamonix.
After he died his wife publishing his investigations and work, before she started re-exploring. She later worked with her (and Alexei's) son Boris Fedtschenko, but Olga remained an important botanist in her own right.
He also discovered the life cycle of Dracunculus which causes Dracunculiasis, more commonly known as Guinea worm disease (GWD).
Accounts of the explorations and discoveries of Fedchenko were published by the Russian government: his Journeys in Turkestan in 1874, In the Khanat of Khokand in 1875, and Botanical Discoveries in 1876. See also Petermann's Mittheilungen (1872–1874).
The botanical epithets 'fedtschenkoi' and 'fedtschenkoanus' may each refer to either to Alexei Fedtchenko, or his son Boris Fedtchenko. Primula fedtschenkoi (Regel) was named after him in 1875., Bambusa fecunda fedtschenkoi , may have been named after him. Also a lacewing in 1875, lopezuz fedtschenkoi (MacLachlan).
