While the specific origin of the name "Orion" is unknown, it is generally accepted that the constellation was named after this mythological figure.

The name "Orion" has been used for centuries, with its first recorded use in Greek literature dating back to Homer's epic poem "The Odyssey" written in the 8th century BC.
