Oktawiusz Radoszkowski

and in Polish sources as Oktavij Vikentij Burmejster-Radoškovski) (Russian: Октавий Иванович Радошковский; 7 August 1820 – 13 May 1895) was a Polish entomologist who specialised in Hymenoptera and worked in the Russian Empire.

He published very many scientific papers describing new taxa and on the structure and taxonomic significance of the genitalia of Aculeate Hymenoptera.

Radoshkovsky was born in Łomża in a noble family and was trained in the army, serving as an artillery officer who retired as a Lieutenant-General in 1879.

He described numerous species of Chrysididae, many of which were collected by others such as Alexei Pavlovich Fedchenko (1844–1873).

Most of his specimens, nearly 40000 at the time of transfer, finally went to the Polish Academy of Sciences in Krakow, Jagellonian University and the Zoological Museum of Moscow University.
