The name Kellerberrin is Aboriginal, and is derived from the name of a nearby hill. The hill was first recorded as "Killaburing Hill" by an explorer in 1861, but in 1864 the explorer Charles Hunt recorded it as Kellerberrin Hill. One source claims that Kellerberrin is the name for the fierce ants that are found in the area, while another gives it as meaning "camping place near where rainbow birds are found" - kalla means camping place or place of, and berrin berrin is the rainbow bird
