Castiel

What does Castiel mean?

Castiel is best known as the name of the angel character in the television series Supernatural. Its celestial association gives it a striking, otherworldly quality, while the familiar ending shared with names such as Gabriel and Daniel makes it feel recognisably name-like.

The name is often connected with Cassiel, a figure in later angelic tradition, but a settled literal meaning for the exact spelling Castiel has not been established. For parents, its appeal lies less in a dictionary meaning than in its thoughtful, powerful sound and angelic imagery.

Historical Context

Castiel became widely recognised through Supernatural, in which Castiel is an angel introduced in 2008. The form appears to have been shaped in relation to Cassiel, the name of an angel found in post-biblical and medieval angelic traditions. Cassiel is commonly given Hebrew-based explanations, but the derivation and meaning of Castiel itself are not securely documented. Castiel is therefore best understood as a modern fictional given-name form with older angelic associations.
