Meaning & Origin
A diminutive of the male given name Robert.
Rob is a boy's baby name of Germanic origin, the classic short form of Robert — from the Old Germanic Hrodberht, meaning 'bright fame' (from hrōd, 'fame' + beraht, 'bright'). Rob is the unpretentious, grounded version of a name that has been carried by kings, saints, and the legendary Robin Hood — bright fame worn lightly.
Rob is Robert at its most relaxed — the bright fame of Germanic nobility compressed into one syllable, stripped of any ceremony, carried by someone who doesn't need to announce himself because everyone already knows who he is.
