Roger J. H. Collins (born 2 September 1949[1]) is an English medievalist, currently an honorary fellow in history at the University of Edinburgh.
Collins studied at the University of Oxford (Queen's and Saint Cross Colleges) under Peter Brown and John Michael Wallace-Hadrill.
His research has primarily concerned the Early Middle Ages, with an emphasis on Spain, but also the Franks.
His studies on the Basques and the Papacy (ongoing) have extended beyond this medieval period into the modern.
His most recent publication is a book on the seventh- and eighth-century versions of the Chronicle of Fredegar for the Monumenta Germaniae Historica.
