Archpriest was a title given to a high spiritual leader in Romulan culture.

In 2374, Archpriest N'Gathan plotted the assassination of the Romulan Emperor Shiarkiek. (ST short story: "Blood Sacrifice")

In the late 2370s, Archpriest Tamok was a highly respected figure in Romulan society. He was expected to visit the Federation in early 2380 to meet newly elected Federation President Nanietta Bacco, though this was a deception created by Romulan Ambassador T'Kala.
