The small fish-shaped symbol you sometimes see on the back of a car is usually a Christian ichthys (fish) symbol.
It is an ancient Christian symbol. The Greek word “ichthys” (ἰχθύς) means “fish,” and early Christians used the fish as a discreet way to identify themselves and their faith.
The symbol is commonly interpreted as an acronym based on the Greek phrase:
Ἰησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ
“Jesus Christ, Son of God, Savior.”
Why put it on a car?
Today, someone may place the fish emblem on their vehicle as a personal expression of Christian faith or to identify themselves as a Christian. It isn’t a special vehicle designation, warning sign, or indication that the driver belongs to a particular organization.
You’ll sometimes see variations, including a fish with the word “Jesus” inside it or other modifications. Some of these have additional cultural or religious meanings.
So if you see the simple fish symbol on a car, the most likely meaning is simply: “The owner is identifying with Christianity.”
