Sa'id ibn Makhlad (Arabic: سعيد بن مخلد) (died 889) was a senior official of the Abbasid Caliphate.

Born a Nestorian Christian, he converted to Islam and served as a secretary in the Abbasid capital, Baghdad.

His valuable assistance to al-Muwaffaq was recognized in 882 by the award of the honorific title Dhu'l-wizaratayn ("possessor of the two vizierates"), with which he appears even on coins.

Sa'id has been erroneously considered by some writers as the brother of another Christian convert, al-Hasan ibn Makhlad al-Jarrah, who was his predecessor as vizier.
