Windsor is a historic town north-west of Sydney, New South Wales, Australia.

A horseshoe on the outside wall of the Macquarie Arms pub marks the level the flood peaked at in 1867.

The Windsor area was originally inhabited by the Dharuk (also Darug) nation of indigenous aboriginal peoples.

Settlement at the location was first established circa 1791, near the head of navigation on the Hawkesbury River (known as Deerubbin in Dharuk).

Governor Lachlan Macquarie "marked out the district of Green Hills", which he "... called Windsor", after Windsor-on-the-Thames.

Of these new buildings, the most outstanding was Francis Greenway's St Matthew's Anglican Church.

In 1813 a report was given to Governor Macquarie from Earl Bathurst detailing a proposed invasion of the Hawkesbury River by France.

[4] This planned invasion that did not eventuate targeted the Windsor granary in order to cut off supply to Sydney, demonstrating the relative importance of this new settlement on a global scale.

Pitt Town, which is 9.3 km (5.8 mi) north west of Windsor, was a filming location for the Channel 7 television series A Country Practice.

The opening credits featured the former Court House Hotel, Windsor at 37–39 North Street as the doctor's clinic.

The markets contain stalls selling jewellery, books, arts and crafts, paintings, fashion items, fresh locally grown produce, locally produced jams and many food and drink stands.
