Arcadia is a semi-rural suburb of Sydney, in the state of New South Wales, Australia 42 kilometres north-west of the Sydney central business district in the local government area of Hornsby Shire.

Arcadia is derived from Arcadia, a region in Greece and in Greek mythology was a pastoral retreat.^[2]

Arcadia Post Office opened on 1 December 1895 (renamed from an earlier Upper Galston office) and closed in 1974.^[3]

The original inhabitants of the area were the Darug people.

The name Dooral appeared on Surveyor James Meehan's map of April 1817 and originally covered the whole area which includes present day Arcadia, as well as Dural, Glenorie and Galston.^[4]

Timber cutters opened up the area from 1817 and the early settlements were originally known as Upper, Middle, Lower, North and Little Dural. The name Arcadia was given to a public school that opened in this area in 1895 and was later adopted for the suburb.^[4]
