Newburgh (), formerly an incorporated village, retains the status of a designated place in the Canadian census data. It is situated on the Napanee River, and was first founded in 1822 by Benjamin Files and Wm. V. P. Detlor. It quickly became a thriving community and home to numerous mills. Two saw mills were first built along the river in 1822 and 1825, followed by a grist mill in 1828, two flour mills in 1840, an oatmeal mill in 1861, two carding mills and a woollen mill in 1864. Other businesses such as a tannery, two axe factories, a sash, blind and door factory, a hub and rake factory, three carriage and wagon shops and two cabinet factories were also established.
