Abba Gorgoryos Ge'ez: ጎርጎርዮስ (sometimes transliterated in English as Gorgorios, Gregorius, and so on; meaning Father Gregory) (1595 in Mekane Sellasie in Amhara Province – 1658 in İskenderun) was an Ethiopian priest and lexicographer of noble origin. He is famous for co-authoring encyclopedias with his friend and companion Hiob Ludolf in two Ethiopian languages, Amharic and Ge'ez, both in Ge'ez script.
Abba Gorgoryos was invited to Gotha in 1652 by Ludolf, who at the time was in the service of Ernest I, Duke of Saxe-Gotha. Lodolf and the Duke were interested about Ethiopia and prepared a list of queries which were presented to Abba Gorgoryos. The Duke took particular interest in the legend of Prester John, while Ludolf was interested in Christianity in Ethiopia and the teaching of the Ethiopian Orthodox Tewahedo Church. The findings of Ludolf is included in his work Theologica aethiopica.
Abba Gorgoryos worked with Hiob Ludolf in co-authoring the earliest grammar of the Amharic language, as well as an Amharic-Latin dictionary, which became the first African language to be translated to Latin. Ludolf's book A History of Ethiopia was based in part on Abba Gorgoryos's conceptualization of Ethiopia and letters. Abba Gorgoryos also developed a Ge'ez lexicon.
On his return to Ethiopia in 1658, he died in a shipwreck off the Turkish city of İskenderun.
