Osbirt is English in Origin.

Osbirt is a rare medieval English variant of Osbert, ultimately from Old English Ōs “god, divine power” + beorht “bright, famous.” The combined sense is “divinely bright” or “god-bright,” often interpreted as “radiantly renowned.” Early spellings include Osbeorht and Osberht, with the Latinized form Osbertus appearing in ecclesiastical records. Orthographic fluidity in Middle English accounts for variants such as Osbirt, Osburt, and Osbart alongside the standard Osbert.

The name was well established in Anglo-Saxon and Anglo-Norman England, borne by figures like King Osberht of Northumbria (9th century) and the 12th-century cleric Osbert of Clare. It occurs in the Domesday milieu and later tax and court rolls before declining after the late Middle Ages. Osbirt and its kin linger sporadically in Scottish and northern English records and sometimes as a transferred surname. Modern bearers are uncommon; potential diminutives include Bert, Oz, and Ozzie. Not to be confused with Osborne/Osborn (Norse Ás + bjǫrn).
