Mar Raphael I Bidawid (Syriac: ܪܘܦܐܝܠ ܩܕܡܝܐ ܒܝܬ ܕܘܝܕ, Arabic مار روفائيل الاول بيداويد) (April 17, 1922 – July 7, 2003) was the Patriarch of the Chaldean Catholic Church from 1989–2003.

Mar Raphael Bidawid was then appointed bishop of Beirut, Lebanon in 1966 and served in this capacity for 23 years.

On March 21, 1989 Raphael I Bidawid was elected Patriarch of Babylon, head of the Chaldean Catholic Church.

In November of 1996, Mar Dinkha IV of the Assyrian Church of the East and Raphael I Bidawid of the Chaldean Catholic Church met in Southfield, Michigan, and signed a Joint Patriarchal Statement that committed their two churches to working towards reintegration and pledged cooperation on pastoral questions such as the drafting of a common catechism, the setting up of a common seminary in the Chicago-Detroit area, the preservation of the Assyrian language, and other common pastoral programs between parishes and dioceses around the world.

It restated the areas of pastoral cooperation envisaged in the Joint Patriarchal Statement, recognized that Assyrians and Chaldean Catholics should come to accept each other’s diverse practices as legitimate, formally implemented the establishment of an Assyrian-Chaldean “Joint Commission for Unity,” and declared that each side recognized the apostolic succession, sacraments and Christian witness of the other.
