Singletons Mill is a suburb of Sydney, in the state of New South Wales, Australia.

It is located in the Hornsby Shire local government area.

James and Benjamin had established a flour mill on Wheeny Creek near Kurrajong and later applied for land on the Hawkesbury River to set up a tidal mill, prior to 1820.

The water-driven wheel was five metres in diameter, and the grinding stones weighed one ton each.
