Edgecliff takes its name from its location because it literally sits on the edge of a cliff. The rocky cliff was extensively quarried in the early day of European settlement. The area was dominated for some time by the Glenrock property, on the north side of New South Head Road. Sir Edward Knox built Fiona in 1864 after having it designed by J.F.Hilly. It has been described as "a Classical Revival two-storey mansion" and was made of sandstone. Other elements of the estate included Glenrock, an Italianate residence designed by David MacBeath and built by John Marks circa 1870. There were also substantial gates of wrought iron and sandstone. The building was demolished when New South Head Road was widened, but the gates survived.

In September 1894 a cable tram service opened, which operated from King Street in the city to Ocean Street in Edgecliff. The powerhouse driving it was located at Rushcutters Bay. Unlike other trams of the era which were driven by steam, the cable ran in a gutter between the tracks. The cars gripped the moving cable to advance and released it to stop. It operated until 1905 when the tram line was electrified. Edgecliff railway station opened in 1979, when the Illawarra line was extended from Town Hall railway station to Bondi Junction.
