Barker College is an independent Anglican co-educational early learning, primary and secondary day and boarding school, located in Hornsby, a North Shore suburb of Sydney, New South Wales, Australia.

In 1939, Barker College was incorporated pursuant to the provisions of the Anglican Church of Australia (Bodies Corporate) Act 1938.

An outbreak of scarlet fever in 1894 convinced Plume that the School was too isolated and would be better located nearer to Sydney.

Thus the School moved to its present site in Hornsby in 1896, and in 1919 its ownership transferred to the Church of England.

The earliest record of the motto is on an illuminated address presented to Rev and Mrs Plume on their departure from the School in 1905.

[23] In 2016 the school opened an Indigenous campus, Darkinjung Barker, at Yarramalong on the NSW Central Coast, for students in Kindergarten to Year 6.

The Junior School has 6 six Houses that were named after explorers of Australia and Antarctica: Byrd, Flinders, Hillary, Mawson, Scott & Tasman.

[29] In July 2018 the College announced they would be changing the pastoral care system for the middle and senior school following the introduction of coeducation.
