Saint Abo of Tiflis or Abo Tbileli (in Georgian: აბო თბილელი, Arabic: أبو تبليسي Abu al-Tiflisi) (ca. 756-January 6, 786) is a Christian martyr and the Patron Saint of the city of Tbilisi, Georgia.
Iraqi by origin, Abo grew up Muslim in Baghdad. At the age of seventeen or eighteen, he found himself in Tbilisi, having followed Georgian Prince Nerses, the ruler of Kartli. Nerses, having been slandered before the Caliph, spent three years in confinement; freed by a new Caliph, he took Abo with him.
