Woodburn is a small highway town on the banks of the Richmond River in New South Wales, Australia.

Prior to the arrival of European settlers in the 1840s, the Woodburn area—known as Maniworkan to the Indigenous inhabitants—was the home of the Bundjalung people.

Woodburn is part of the Richmond Valley Shire, the administrative headquarters of which is in nearby Casino.

Huge flooding inundated the town for days in February 2022, destroying many homes, businesses and vehicles.

Rocky Mouth Creek flows into the Richmond River from the southern end of the town.
