Middle Dural is a semi-rural suburb of Sydney, in the state of New South Wales, Australia, 37 kilometres (23 mi) north-west of the Sydney central business district in the local government areas of Hornsby Shire and The Hills Shire. Dural is a separate suburb to the south.

Dural is derived from Dooral-Dooral, an Aboriginal name meaning a smoking hollow tree. The original inhabitants of the Dural area were the Darug people. The name Dooral appeared on Surveyor James Meehan's map of April 1817 and originally covered the whole area including present day Glenorie, Galston, Arcadia and Dural. Timber cutters opened up the area in the early 19th century and the settlements were originally known as Upper, Middle, Lower, North and Little Dural. Located on the Old Northern Road, a historic road built by convicts between 1825 and 1836 to link early Sydney, in the Colony of New South Wales, with the fertile Hunter Valley to the north. In 1831 George Best established the Half-Way Inn at Middle Dural.

Since the 1970s the Banana Cabana Primate Sanctuary has existed in Middle Dural as a retirement facility for ex-circus and zoo monkeys such as hamadryas baboons, long-tailed macaques, rhesus macaques, black-handed spider monkeys, brown capuchins, common marmosets and even a tortoise species (leopard tortoise).
