Johann Centurius Hoffmann Graf von Hoffmannsegg (23 August 1766 – 13 December 1849) was a German botanist, entomologist and ornithologist.

He travelled through Europe acquiring vast collections of plants and animals.

He sent his collections to Johann Karl Wilhelm Illiger, then in Brunswick, so that he could study them.

Hoffmannsegg worked in Berlin from 1804 to 1816, and was elected a member of the Academy of Science of the city in 1815.
