Roger is an English male given name and surname, from the Anglo-Norman French Roger, Rogier, which is itself derived from Germanic words (hroth, hruod and ger) meaning respectively "fame" and "spear". In Anglo-Saxon sources the name is first recorded, in the Dark Age epic poem Beowulf, as Hroðgar ("glorious spear-bearer").
The name is also found in the Netherlands in the form Rutger, and in German as Rüdiger. The Latin form, as used by a few medieval figures, is Rogerius. A Welsh variation is the family name Rosser.
