Meaning & Origin
A diminutive of the female given name Deborah.
Debby is a girl's baby name of Hebrew origin, a diminutive of Deborah, from the Hebrew Devorah, meaning 'bee.' Deborah was a prophetess and judge in the Book of Judges — one of the Bible's most powerful female figures.
Debby was popular alongside Debbie and Debi in the 1950s and 60s when shortened forms were fashionable. Singer Debby Boone's 1977 hit 'You Light Up My Life' kept this spelling in the spotlight. It's cheerful and approachable — a name that smiles when you say it.
