The Hunter Valley Floods (also known as the Maitland Flood) of 23 February 1955 was a major flood on the Hunter River in New South Wales, Australia. They were one of the most devastating natural disasters in Australia's history.

The flood overwhelmed rivers on both sides of the Great Dividing Range, creating an inland sea the size of England and Wales. Worst hit was the inland city of Maitland, which is sited precariously on low-lying land on the Hunter, and which on this occasion was completely inundated by floodwaters. A total of 25 lives were claimed during a week of flooding that washed away 58 homes and damaged 103 beyond repair. In Maitland alone, 2,180 homes were invaded by water.
