Georg-Maria Schwab (, ; 3 February 1899 – 23 December 1984) was a German-Greek physical chemist recognised for his important contributions in the field of catalysis and the kinetics thereof.
Schwab's early academic career in Berlin and Würzburg (1923–1928) was characterised by meticulous experimental work as a kineticist, before starting his specialisation in heterogeneous catalysis in Munich (1928–1938). Dismissed by Nazi Germany on anti-Semitic grounds, he emigrated to Greece with the help of his future wife Elly Schwab-Agallidis, where together, they continued conducting physico-chemical research (1939–1950).  Eventually returning to West Germany in the 1950s, Schwab served as professor of physical chemistry in the University of Munich until retirement (1951–1967).
