Rautio is a former municipality, now a small village of Kalajoki, Finland. It was consolidated to Kalajoki in 1973.
The name Rautio comes from a word meaning "blacksmith". Rautio has existed at least since 1547, at the time it only had three farms. It was a part of the Kalajoki parish.
Rautio became a chapel community in 1826. In 1912, it became a separate parish and municipality.[1]
Rautio was merged back into Kalajoki in 1973.
