Qaafiyaa or Qafiyah (Persian: قافیہ‎) is a device employed in a form of Persian poetry and Urdu poetry known as Ghazal (a poetic form consisting of couplets which share a rhyme and a refrain) and also in Nazm. The Qaafiyaa is the rhyming pattern of words that must directly precede the Ghazal's Radif. The example below is of a Ghazal below by Daag Dehelvi. In this case the Qaafiyaa is the following pattern of words: jalwa-gaah, nigaah, raah, haale-tabaah and aah. The Radif is mein. وہ حروف جو روی کے بعد آتے ہیں وہ حرف وصل، حرف خروج، حرف مذید اور حرف نائرہ کہلاتے ہیں۔
