Olgaea is a genus of Asian plants in the tribe Cardueae within the family Asteraceae, having a typical thistle appearance.

In 1922, Modest Mikhaĭlovich Iljin (from the Botanical Garden of the Academy of Sciences of Soviet Russia) named the genus in honour of Russian botanist Olga Fedtschenko (1845–1921).

Olgaea's genome consists of a diploid number of 2n=26 chromosomes.
