Roman Ulrich Sexl (19 October 1939 – 10 July 1986) was one of the leading Austrian theoretical physicists. He is famous for his textbooks on Special relativity.

His most cited work is "On the gravitational field of a massless particle" together with Peter C. Aichelburg. Since 1972 he was professor for Cosmology and General Relativity at the University of Vienna. From 1971 to 1975 he was the director of the Institute for Space Exploration at the Austrian Academy of Sciences.

In 1980 he received the Robert Wichard-Pohl prize. Today there is the annual Roman-Ulrich-Sexl-Prize for extraordinary achievements in teaching physics.
