Gregorios Abdul Jaleel (1605–1681) was a Syriac Orthodox metropolitan who served as the Patriarchal Vicar of Jerusalem. Born in Mosul, Iraq, to Abdulahad, he was ordained as a metropolitan in 1653. He is most famous for his 1665 journey to India, an expedition that forged lasting connections between the Syriac Orthodox Church of Antioch and the Malankara Church. During his mission, he ordained both Thoma I and Thoma II as metropolitans, leaving a significant ecclesiastical mark on the Indian Christian community.
