Osbyrt is English, Germanic in Origin.

Osbyrt is a rare variant spelling of the Old English name Osbert, from os "god, divinity" + beorht/berht "bright, renowned," giving the meaning "divinely bright" or "bright fame." The spelling with y recalls medieval orthography and echoes early forms such as Osberht, where the second element preserves the older -berht "bright."

Osbert/Osberht appears in Anglo-Saxon and early medieval England; one bearer was King Osberht of Northumbria (d. 867), and the name persisted into Norman and later Middle English records before fading in the early modern period, with occasional Victorian antiquarian revivals. Documented and plausible variants include Osbert, Osberht, Osbirt, Osburt, and the creative modern Osbyrt; short forms Oz and Ozzy occur by analogy with other Os- names. While exceedingly uncommon today, Osbyrt offers a historically grounded choice with crisp consonants and a luminous, theologically tinged meaning.
