George Ernest Kalmus, CBE, FRS (born 21 April 1935) is a British particle physicist.
Kalmus was born in Beocin, Yugoslavia, and moved to Britain with his parents and his elder brother Peter Kalmus in 1939. His sister Elsa Joan Kalmus was born in 1945. The family became British Citizens in 1946.
Kalmus was Associate Director, 1986–94 and Director, 1994–97 of Particle Physics at the Rutherford Appleton Laboratory.
Kalmus went to school first in Hampstead and then in Harpenden, Hertfordshire. From 1945 till 1956 he was at St Albans County Grammar School (later renamed Verulam School). He received his BSc (1956) and PhD (1959) at University College London where he remained for a further three years as a Research Associate. He is now an Honorary Fellow of University College London.

Kalmus' father, Hans Kalmus, was a well-known biologist who worked at University College, London from 1939, officially retiring as Professor in 1973 but continuing there until his death in 1988 at the age of 82.
His brother, Peter Kalmus, is another noted British particle physicist. A press release from the Particle Physics and Astronomy Research Council(PPARC) in 2002 commented that "A particle physicist in the family is a rare occurrence. That there should be two and both be leaders of the field is even more unusual, yet Professors Peter and George Kalmus have achieved this." 
Kalmus has three daughters.
He currently resides in Abingdon with his wife, Ann Christine (née Harland) Kalmus.
