**George Keith Batchelor** FRS^{[1]} (8 March 1920 – 30 March 2000) was an Australian applied mathematician and fluid dynamicist.

He was for many years a Professor of Applied Mathematics in the University of Cambridge, and was founding head of the Department of Applied Mathematics and Theoretical Physics (DAMTP). In 1956 he founded the influential *Journal of Fluid Mechanics*^{[2]} which he edited for some forty years. Prior to Cambridge he studied at Melbourne High School and University of Melbourne.^{[3]}

As an applied mathematician (and for some years at Cambridge a co-worker with Sir Geoffrey Taylor in the field of turbulent flow), he was a keen advocate of the need for physical understanding and sound experimental basis.

His *An Introduction to Fluid Dynamics* (CUP, 1967) is still considered a classic of the subject, and has been re-issued in the *Cambridge Mathematical Library* series, following strong current demand.^{[4]} Unusual for an 'elementary' textbook of that era, it presented a treatment in which the properties of a real viscous fluid were fully emphasised.^{[5]} He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1959.^{[6]}

The Batchelor Prize award, is named in his honour and is awarded every four years at the meeting of the International Congress on Theoretical and Applied Mechanics.^{[7]}
