Hallam Leonard Movius (November 28, 1907 – May 30, 1987) was an American archaeologist most famous for his work on the Palaeolithic period.

He was born in Newton, Massachusetts and attended Harvard College, graduating in 1930.

In 1948 he proposed the existence of a Movius Line dividing the Acheulean tool users of Europe, Africa and western Asia from the chopping tool industries of East Asia.

He also studied the Perigordian and Aurignacian cultures of Palaeolithic France, excavating at the rock shelter of Abri Pataud in Les Eyzies (Dordogne) from 1958 to 1973.

The American poet Geoffrey Movius (born 21 January 1940) was a son.
