The Brunswick River is a river in the north of the Australian state of New South Wales, which opens out into the Tasman Sea, a marginal sea of the Pacific Ocean.

The main arm of the Brunswick River stretching over 20 km from west to east and is comprised of two arms, a northern and a southern, fed. The northern arm extends over just 5km away and is called Marshall's Creek. The Marshalls Creek flows through the town Ocean Shores. The Marshalls Creek was named after Bob Marshall, an early resident of the town of Brunswick Heads where the river meets the sea. Marshall was a lumberjack and has 1884, the first hotel built in Brunswick Heads. The southern arm of the river bears the name of Simpsons Creek and is about 15 km long.

1828, the river was mapped for the first time by Henry John Rous. 1849 Lumberjack settled in the mouth region and established the first permanent settlement, from which then developed the town of Brunswick Heads over the decades. The most important settlement on the Brunswick River is today but convenient for the interior Mullumbimby.

The Brunswick River transported strikingly large amounts of sediments (about 350,000 m³ per year). In the mouth of the river in the Pacific Ocean is approximately 1 sq. km found on seagrass beds. In addition, the mouth of the river turns, which is characterized by pronounced mangroves, to be beneficial for the local oyster farm in Brunswick Heads.

The Brunswick River has always been transported large amounts of nutrients. However, the river is suffering increasingly from agricultural production in the region, which negatively impacted by the entry of nutrients and poisons its ecosystem.
