Jahan (fa|جهان, Urdu:, bn|জাহান) is a word of Persian origin meaning "world" or "universe". It is used as a gender neutral first name or surname in the Middle East, Central and South Asia. The Turkish rendering of the same name is Cihan.
Along with Jehan, it is also a variant and ancient form of French name and surname Jean. The surnames Jahan and Jehan have been most prevalent in northwestern France (e.g. Normandy, Brittany, Touraine).[1] [2]
