Nadya is a feminine given name, sometimes a short form (hypocorism) of Nadezhda or other names.
Nadya is used predominantly throughout the Mediterranean region, Eastern Europe, Latin America, the Caucasus, and the Arab world. It has also seen some popularity in Quebec, France and Ireland. Its origins are in the Slavic and Ancient Greek languages. Variations include: Nadja, Nadia, Nadine, Nadiya, and Nadiia.
The name Nadya (or Nadia) means "hope" in many Slavic languages, e.g. Ukrainian Nadiya (Надія, accent on the i), Belarusian Nadzeya (Надзея, accent on the e), and Old Polish Nadzieja, all of which are derived from Old East Slavic. In Bulgarian and Russian, on the other hand, Nadia or Nadya (Надя, accent on first syllable) is the diminutive form of the full name Nadyezhda (Надежда), meaning "hope" and derived from Old Church Slavonic, which it entered as a translation of the Greek word ελπίς (Elpis), with the same meaning.
The name's early roots and origins date back to Ancient Greece mythology. In most other languages, it is a name in its own right.
In Arabic, Nadiyyah means "tender" and "delicate".
