Tweed Heads is a coastal city at the mouth of the Tweed River in the Northern Rivers region of the state of New South Wales, Australia. Tweed Heads is the northernmost town in New South Wales, and is located in the Tweed Shire local government area. It is situated 830 km (520 mi) north of Sydney and 103 km (64 mi) south of Brisbane. The town is next to the border with Queensland and is adjacent to its "twin town" of Coolangatta, which is a suburb of the Gold Coast in Queensland.

In 1823 John Oxley was the first European to see the Tweed Valley, and he wrote of it: "A deep rich valley clothed with magnificent trees, the beautiful uniformity of which was only interrupted by the turns and windings of the river, which here and there appeared like small lakes. The background was Mt. Warning. The view was altogether beautiful beyond description. The scenery here exceeded anything I have previously seen in Australia."

Timber cutters originally moved to the Tweed Valley in 1844. After the timber had been cleared, farmers moved in with bananas, cane and dairy farming dominating the area, while a fishing industry developed. The first school opened in 1871.

In May 1888, 119 subdivided lots of "Boyd Estate" were advertised to be auctioned by W. H. Brett. A map advertising the auction shows that the estate was located next to the Tweed River.

The Tweed Heads and Coolangatta Surf Life Saving Club opened on 13 September 1911.

In April 1916, 69 allotments of "Charles' Tweed Heads subdivision were advertised to be auctioned by P. Smith & Son. A map advertising the auction shows the location of the estate in proximity to Terranora Creek.

In November 1917, 46 subdivided allotments of "Marks Estate" were advertised for auction by S. A. Thornton. A map advertising the auction illustrates the location of the estate in proximity to Terranora Creek, Coolangatta and the Pacific Ocean and describes the allotments as perfectly flat, large areas with splendid frontages.

The Tweed Shire, inclusive Murwillumbah was declared in 1947.
