Iluka is a small village at the mouth of the Clarence River in New South Wales, Australia. It is situated directly across the river from the resort town of Yamba. At the 2006 census, Iluka had a population of 1,739 people. The town's name is derived from an aboriginal word meaning "near the sea".
It has long beaches on the ocean side of the river. It is reached by turning off the Pacific Highway approximately 20 kilometres north of Maclean. As Iluka is a popular tourist destination its population increases slightly in the holiday season with many Gold Coasters in the summer and Victorians in the winter.
