Meaning & Origin
JD is a boy's and girl's baby name used as an independent given name, typically standing for a combination of names beginning with J and D — most often James David, John David, or similar pairings. The initials-as-name tradition has a long history in American naming culture.
JD gained cultural visibility through the sitcom Scrubs (2001–2010), where the protagonist went by JD throughout the show, helping establish the initials as a standalone identity rather than just an abbreviation.
