Melchizedek I (Georgian: მელქისედეკ I) was the first Catholicos-Patriarch of All Georgia, from 1010 to 1033,[1] reigning from Ani.

Before him, heads of the Georgian Church only bore the title of Catholicos of Kartli.

The unification of Georgia into a single kingdom by Bagrat III (r. 975–1014) led to the change in title.

[2] He visited Constantinople several times, and met with the Byzantine Emperor Basil II.

[citation needed] Melchizedek was glorified by the Georgian Orthodox Church on October 17, 2002.
