Oakleigh is a suburb of Melbourne, Victoria, Australia and is located 14 km south-east from Melbourne's central business district. Its Local Government Area is the City of Monash. At the 2006 Census, Oakleigh had a population of 6,876.
Once a large independent city, Oakleigh was absorbed into Melbourne as part of the eastward expansion of the metropolis in the 1950s. As a result, it once had its own large historic Central Business District, its own municipality in the former City of Oakleigh and its own suburbs.
The area is traditionally known to have a strong Greek cultural influence, largely due to the influx of said immigrants to Australia in the mid-20th century. Fourteen per cent of those living in the suburb speak only Greek at home.
The origins of the name of the suburb, "Oakleigh," is unclear, local historians have three main theories - that it was derived from she-oaks that grew near Scotchmans Creek; from "Oakleigh Park" an estate near Malvern Hills in England; or from Mrs. Oakley an early settler.
