Walter Beick (1 October 1883 – 25 March 1933) was a Baltic-Russian ornithologist who explored and studied the birdlife of Tibet and Mongolia.

He then settled in Russian Turkestan and from 1916 began to make hunting trips from the Ala-tau mountains.

In 1920, he was forced to give up all his possessions including his collections to the Bolsheviks and fled to Chinese Turkestan, where he lived by hunting and fishing.

He joined Birger Bohlin of the Sino-Swedish Expedition led by Sven Hedin and spent some time in Tsag Nor and was hoping to return to Germany.

He was buried in the desert with a cross inscribed "Walter Beick, 25 March 1933" at 42° N, 101° 19′ 6″ E.[1][2] Subspecies that have been named after him include the following, although not all are now considered valid.
