Saad (Arabic: سعد, romanized: Saʿd) is a common male Arabic given name.
The name stems from the Arabic verb sa‘ada (سَعَدَ 'to be happy, fortunate or lucky').
Saad is the stem of variant given names Suad and Sa‘id.
It may be a shortened version of Sa'd al-Din, and is not to be confused with it.
It is not the same as the single Arabic letter ṣād, which has no intrinsic meaning.
