Benacre is a house in Glen Osmond, (an inner south-eastern suburb of Adelaide, South Australia), which was listed on the now-defunct Register of the National Estate.

The settlement was made and administered by the South Australia Company, who also released land in the city and on the Adelaide Plains.

[5] After the loss of a baby in the summer conditions of the city in December 1845, William Bickford, desiring to escape the unhealthy conditions of his city residence, purchased 16 acres in early 1846, and added to the buildings on the property, including building the stables and coach house which are now registered on the Australian Register of the National Estate.

Thomas Graves established a fine garden containing Moreton Bay figs, pines, cedars and cypresses from such diverse places as Norway, India, Lebanon, Japan and Norfolk Island - "an assortment of trees second only to the Adelaide Botanic Garden", according to the book "History of Glen Osmond", (1905).

In 1906, John Lewis, pastoralist and politician, moved to Adelaide "where he bought an imposing home, Benacre, at Glen Osmond".
