David Littmann (July 28, 1906 – January 1, 1981) was an American cardiologist and Harvard Medical School professor and researcher. The name Littmann is well known in the medical field for the patented Littmann Stethoscope reputed for its acoustic performances for auscultation.

Littman was born on July 28, 1906 in Chelsea, Massachusetts. His parents, Isaac Litman and Sadie Zewat Litman, were Ukrainian immigrants from Novgorod.

With Gustev Machlup, Dr. David Littmann founded Cardiosonics, Inc. to sell his stethoscopes. At that time the stethoscope line consisted of two key models, the doctor's stethoscope and the nurse's stethoscope.

3M acquired the stethoscope company on April 1, 1967, and hired Dr. Littmann as a consultant. 3M currently produces the range of Littmann brand stethoscopes.

The 1960s-era Littman Cardiology 3 stethoscope, which is out of patent, became the basis of a 3D-printed stethoscope developed by Dr. Tarek Loubani and a team of medical and technology specialists as part of the open source Glia project.

Dr. Littmann's son was jazz drummer Peter Littman (1935-1985).
