Paul I Peter Massad, or Boulos Boutros Massaad (also Mas'ad; Arabic: بولس الأول بطرس مسعد; 16 February 1806 – 18 April 1890) was the 70th Maronite Patriarch of Antioch from 1854 until his death in 1890.

Paul Peter Massad was born in the village of Ashqout, in the Keserwan District, Lebanon on February 16, 1806.

One of his first acts as Patriarch was to hold a national synod of the Maronites, in Bkerké, in April 1856, under the presidency of the papal legate of Syria, Paul Brunoni.

[4] A man of culture, Massad wrote several works among which are mentioned: a book of the characteristics of the Eastern Churches; about the procession of the Holy Spirit; a treatise of the perpetual virginity of the Mother of God; several dissertations about the Maronites and a historical account of Khazen family.

From a religious point of view, Massad fully established the Maronite Church within the Roman framework while maintaining many of its own distinctive elements.
