Elizabeth Vladimirovna Kozlova née Pushkariova (19 August 1892 – 10 February 1975) was a Russian ornithologist who worked on the avifauna of the Tibetan plateau.

In 1910, at the age of 18, she was in Normandy where she impressed the famous Colonel Pyotr Kozlov, a well-known explorer 29 years her senior.

[3] From 1923–1926 she took part as the professional ornithologist in an expedition, organised by the Russian Geographical Society and led by her husband, to Mongolia.

[1][2] Kozlova was based at the Department of Ornithology in the Zoological Institute of the Russian Academy of Sciences in Saint Petersburg (then Leningrad) from 1932 to 1975.

She then produced the monographs Avifauna of the Tibetan Plateau, its Genetic Relationships and History in 1952, and The Birds of Zonal Steppes and Deserts of Central Asia in 1975.
