Meaning & Origin
A diminutive of the male given name Geoffrey.
Geoff is a boy's baby name of German origin, a short form of Geoffrey, derived from the Germanic elements meaning 'territory' and 'peace' or from Godfrey meaning 'God's peace.'
While Geoffrey has a long distinguished history — including Geoffrey Chaucer, father of English literature — Geoff as a standalone name carries a relaxed, modern British charm. It's the kind of name that feels both classic and effortlessly casual, particularly popular in the UK and Australia.
