René Lodewijk Maurits Derolez (7 September 1921 – 24 March 2005) was a Belgian philologist who was Professor of English and Germanic Philology at Ghent University. He specialized in runology and the study of Old English literature and Germanic religion.
René Lodewijk Maurits Derolez was born in Aalst, Belgium on 7 September 1921. During the German occupation of Belgium during World War II, Derolez studies Germanic philology at the Ghent University.

He received an MA at Harvard and his PhD summa cum laude at Ghent in 1947. He gained his habilitation at Ghent in 1954 with the thesis Runica Manuscripta.

Delorez specialized in the study of early Germanic culture, particularly runes, Old English literature (particularly Beowulf) and Germanic religion and Germanic mythology. His books on Germanic religion won him wide acclaim, and were translated into several languages.
During his studies at Harvard, Delorez met Gabrielle von Steiger, daughter of Swiss politician Eduard von Steiger, and the two subsequently married. His brother Albert Derolez is a medievalist and professor at the Free University of Brussels.
