Historically, the village of Hafslo was the administrative centre of the municipality of Hafslo, which existed from 1838 until 1963. Hafslo Church, located in the village of Hafslo, was the main church for the municipality, and it still is the main church for the Hafslo parish.

The name comes from the old Hafslo farm (Old Norse: Hafrsló), since Hafslo Church was located there. The first element of the name comes from the old male name Hafr or from the word for "goat" (also hafr). The second element of the name comes from the old word ló meaning "meadow", probably due to the excellent farming areas nearby.
