The year 1931 in science and technology involved some significant events, listed below.

Astronomy

• French astronomer Bernard Lyot invents the coronagraph.

Chemistry

• November 26 – Harold Urey and associates at Columbia University discover deuterium by the fractional distillation of liquid hydrogen, leading to demonstration of the existence of heavy water.
• Erich Hückel proposes Hückel's rule, which explains when a planar ring molecule will have aromatic properties.
• The first aerogel is created by Steven Kistler.

Earth sciences

• Modified Mercalli intensity scale introduced as a seismic scale for earthquakes in the United States.

History of science

• Het Nederlandsch Historisch Natuurwetenschappelijk Museum ("The Dutch Historical Museum of the Natural Sciences") opens in Leiden.

Mathematics

• January – Kurt Gödel's "On Formally Undecidable Propositions..." is published in Monatshefte für Mathematik.

Physics

• Ernst Ruska and Max Knoll build the first prototype electron microscope.
• Paul Dirac proposes that the existence of a single magnetic monopole in the universe would suffice to explain the quantization of electrical charge.

Physiology and medicine

• May–October – American pathologists Ernest William Goodpasture and Alice Miles Woodruff publish their results on growing influenza and several other viruses in fertilised chicken eggs. Richard Shope publishes three papers identifying influenza A virus as the cause of swine influenza.
• December 3 – The drug Alka-Seltzer is placed on the market.
• Adolf Butenandt discovers androsterone.
• John Haven Emerson and August Krogh introduce new forms of negative pressure ventilator.

Technology

• May 27 – Swiss-born scientist Auguste Piccard and his assistant, engineer Paul Kipfer, taking off from Augsburg, Germany, reach a record altitude of Шаблон:Convert in a balloon with a pressurized gondola, gathering data on the upper atmosphere and measuring cosmic rays, the first human flight into the stratosphere.
• October 5 – American aviators Clyde Edward Pangborn and Hugh Herndon, Jr., complete the first non-stop flight across the Pacific Ocean, from Misawa, Japan, to East Wenatchee, Washington, in 41½ hours.
• October 24 – The George Washington Bridge across the Hudson River in the United States is dedicated; it opens to traffic the following day. At Шаблон:Convert, it nearly doubles the previous record for the longest suspension span in the world.
• December 14 – British electronics engineer Alan Blumlein of EMI submits a UK patent application for "Improvements in and relating to Sound-transmission, Sound-recording and Sound-reproducing Systems" – binaural or stereophonic sound.
• László Bíró first exhibits his ballpoint pen, in Budapest.
• George Beauchamp invents the electric guitar.
• John H. Sharp of Chicago files the first patent for a torque wrench.
• Construction of the Hoover Dam begins on the Colorado River in the United States (chief designing engineer: John L. Savage).

Other events
