Iffley Road is a major arterial road in Oxford, England. It leads from the Plain, near Magdalen Bridge, southeast towards the village of Iffley. While it becomes Henley Avenue at Iffley Turn, and then Rose Hill, the whole stretch from the ring road to the Plain is referred to by some as Iffley Road. Formerly named as Henley Road in the 19th century, as it leads towards Henley-on-Thames, this entire route is designated the A4158.
