Alexander Behm (born 11 November 1880 in Sternberg (Mecklenburg); died 22 January 1952 in Tarp (Schleswig-Flensburg)) was a German physicist.

As head of a research laboratory in Vienna (Austria) he conducted experiments concerning the propagation of sound. He tried to develop an iceberg detection system using reflected sound waves after the Titanic disaster on 15 April 1912. In the end reflected sound waves proved not to be suitable for the detection of icebergs but for measuring the depth of the sea, because the bottom of the sea reflected them well. Thus, echo sounding was born.

Behm was granted German patent No. 282009 for the invention of echo sounding (device for measuring depths of the sea and distances and headings of ships or obstacles by means of reflected sound waves) on 22 July 1913.

In 1920 he founded the Behm Echo Sounding Company in Kiel in order to commercialise his invention.
