Abercius of Hieropolis (Ancient Greek: Ἀβέρκιος; died c. 167) was a Christian clergyman from Hierapolis at the time of Roman emperor Marcus Aurelius.

He states that "The confusion of the two towns Hierapolis and Hieropolis has produced much error in early Christian history.

"[6] The Catholic Encyclopedia notes that Ramsay "discovered at Kelendres, near Synnada, in Phrygia Salutaris (Asia Minor), a Christian stele (inscribed slab) bearing the date of the year 300 of the Phrygian era (216 AD).

Mr. Ramsay, on a second visit to the site of Hieropolis, in 1883, discovered two new fragments covered with inscriptions, built into the masonry of the public baths.

These fragments, which are now in the Vatican Christian Museum, filled out the middle part of the stele inscribed with the epitaph of Abercius.
