Bernard Gregory (19 January 1919, Bergerac – 24 December 1977, Élancourt) was a prominent French physicist and director-general of CERN.

During World War II, Gregory was a prisoner of war in a German camp for military officers. After the war he graduated from the École Polytechnique and École Nationale Supérieure des Mines de Paris, then went to the United States to study fundamental particle interactions in high-energy cosmic rays.

After earning his Ph.D. in 1950 at MIT, under the supervision of Professor Bruno Rossi, Gregory returned to France. He became known in the high energy physics world in the 1950s when he worked as a researcher, with the title of deputy director, under Professor Leprince- Ringuet at the École Polytechnique. At the École Polytechnique he worked with a number of physicists including , Jean Crussard, , and later André Astier.

In 1958, Gregory was appointed professor of physics at the Polytechnique. Around 1960, Gregory got involved in the bubble chambers research. He directed the work on the 81 cm Saclay Bubble Chamber, developed by the technical services at Saturne for the laboratory of the École Polytechnique, and was subsequently brought to CERN PS in Geneva.
