Brailey Sims (born 26 October 1947) is an Australian mathematician born and educated in Newcastle, New South Wales. He received his BSc from the University of New South Wales in 1969 and, under the supervision of J. R. Giles, a PhD from the same university in 1972. He was on the faculty of the University of New England (Australia) from 1972 to 1989. In 1990 he took up an appointment at the University of Newcastle (Australia). where he was Head of Mathematics from 1997 to 2000.

He is best known for his work in nonlinear analysis and especially metric fixed point theory and its connections with Banach and metric space geometry, and for his efforts to promote and enhance mathematics at the secondary and tertiary level.
