The High Priest of Ra or of Re was known in Egyptian as the wr-mꜢw, which translates as Greatest of Seers.
The main cult of Ra was in ancient Heliopolis, northeast of present-day Cairo. The high priests of Ra are not as well documented as the high priests of other deities such as Amun and Ptah.

The Al-Masalla area of the Al-Matariyyah district, the site of Heliopolis, contains the underground tombs of High Priests of Re of the Sixth Dynasty (2345 BCE—2181 BCE), which were found in the southeast corner of the great Temple of Re—Atum archaeological site. The ancient Masalla Obelisk, or El-Misalla (Arabic: المسلة, trans. obelisk), in Al-Matariyyah is the only surviving element standing of the Re—Atum Temple, constructed by Pharaoh Senusret I (1971 BCE—1926 BCE) of the Twelfth Dynasty.
