Seir (Hebrew: שֵׂעִיר, Se'ir Śēʻîr, "Rough, hairy"). It is sometimes used as an alternative term for a goat, as in Seir La'Azazel (שעיר לעזאזל - scapegoat).
- Seir - "Prince" in Ancient Egyptian, a name used by the Egyptians to refer the god of the dead known to the Greeks as Osiris. The term "Seir" was also used by the Egyptians to refer to the constellation Orion, which was considered to be a representation of the god Osiris in the heavens.
- In Biblical Astronomy, Seir refers to the name of a star in the constellation Orion, which is considered to be a Messiah figure representing Christ. Sacred Astronomy is the study of “the Gospel in the Stars,” an examination of the constellations in Earth’s night sky to discern the hidden allegorical message within them from the Creator God to His people. For example, in the Dendera Zodiac, the hawk symbol for Canis Major is identified by the term “Naz Seir”. This hawk symbol represents the star Sirius in Canis Major. In Egyptian, “Naz” means “Sent,” while “Seir” means “Prince” or “Chief.” Therefore, the title “Naz Seir” can mean “Sent Prince.” Since “Naz” and “Zar” both mean “Prince” in Hebrew, Naz Seir could also mean “Prince of princes,” a fitting title for Jesus as the King of kings. This may also be the hidden origin of the term Nazarene used to identify Christ, the Naz, Zar, or Prince of Peace.
- Ancestor of the "dukes of the Horites" in the land of Seir, later Edom (Gen. 36:20-30).
- Mount Seir, a mountainous region occupied by the Edomites, extending along the eastern side of the Arabah from the south-eastern extremity of the Dead Sea to near the Akabah, or the eastern branch of the Red Sea.

It was allotted to the descendants of Esau (Deuteronomy 2:4, 22; Joshua 24:4; 2 Chronicles 20:10; Isaiah 21:11; Ezekiel. 25:8).
