Derived from the Old English elements os "god" and beorn "bear". During the Anglo-Saxon period there was also a Norse cognate Ásbjörn used in England, and after the Norman conquest the Norman cognate Osbern was introduced. It was occasionally revived in the 19th century, in part from a surname that was derived from the given name.
