NasirudDin

Nasiruddin is a male given name used in many Muslim communities across the Middle East, South Asia, and Central Asia. It derives from Arabic nasir, meaning helper or defender, and din, meaning religion or faith. The combined meaning is commonly understood as defender of the faith or helper of the religion. The name appears in several transliterations, including Nasiruddin, Nasir-ud-Din, Nasiruddin, and, in modern usage, Naseeruddin.

In historical and cultural contexts, the form Nasir al-Din (or Nasiruddin al-Din) has appeared as part of longer names or titles for rulers, scholars, and saints. The spelling varies with language and era, reflecting Persian, Arabic, Turkish, and South Asian influences. In South Asia, the name is frequently rendered as Naseeruddin or Nasiruddin, and it has been used both as a given name and as part of compound royal or scholarly names.

Notable individuals with this name or its variants include Nasir al-Din al-Tusi (1201–1274), a Persian polymath, astronomer, and philosopher influential in medieval science; Naser al-Din Shah Qajar (1831–1896), the Shah of Iran from the Qajar dynasty; and Naseeruddin Shah (born 1950), an Indian actor known for a wide range of film and theater work. The name continues to be used in contemporary contexts, often reflecting a cultural heritage tied to the idea of faith and protection.
