History & Origin

Cain (Hebrew Qayin) is the name of Adam and Eve's firstborn son in Genesis. His murder of Abel is the first homicide in the Bible. The name's etymology may derive from qanah (to acquire) — Eve says she 'acquired' a man. As a given name it has been used despite its dark associations.

Cain has been used as a given name historically in Christian communities. It ranked #974 for boys in 2024.

Did you know? In the Book of Genesis, Eve names her firstborn son Cain saying 'I have gotten a man from the Lord' — the Hebrew word qanah (to acquire) being the folk etymology of the name. So Cain literally means 'I got one' in the first naming event of the Bible.
