Struthio anderssoni, also known as the East Asian ostrich, is an extinct species of ostrich that lived in the Pleistocene and Holocene in China and Mongolia. The youngest dates obtained by mass spectrometry analysis of eggshell fragments reveal that the species survived until at least 8.9 ka BP.

Struthio anderssoni was a large ostrich with an estimated mass of 270kg, laying eggs of up to 2400 cm³ in volume. In 2023, based on a re-examination of cast of a femur, it was suggested that this species be moved to the genus Pachystruthio.
