Byford is a suburb on the south-eastern edge of Perth, Australia, and has its origins in a township that was gazetted under the name "Beenup" in 1906. "Beenup", a corruption of the Aboriginal name associated with nearby Beenyup Brook, was the spelling that had been applied to a railway siding there. The uncorrupted form, "Bienyup" received mention in surveyor Robert Austin's account of an expedition through the area in 1848. In 1920, the name of the township was changed to Byford.
