The 1956 Murray River flood involved the rising of waters in the Murray River and flooding of many towns in New South Wales, Victoria and South Australia. The flood occurred due to higher than average rainfalls in Western Queensland and heavy rains in the proceeding three months in the Murray-Darling basin. Flood waters moved down the Murray and Darling rivers for seven months and peaked between 11 and 14 August at Merbein in Victoria and 12.3 metres (40 ft) at Morgan in South Australia. Some areas were flooded up to 100 kilometres (62 mi) from the natural flow of the river. The flood was and still is considered the biggest flood in the recorded history of the Murray and described as "the greatest catastrophe in South Australia's history", in spite of no lives being lost.
From upstream to downstream, flooding occurred in the towns of Wentworth in New South Wales; Colignan, Iraak, Mildura, Nangiloc, and Red Cliffs in Victoria; and Mannum, Murray Bridge, and Renmark to store high flows from the Darling River.

0 deaths, Hotels in the main street of Mannum operated their bars from the second floor with boats tying up to the balcony. The flood water broke the levee bank on 24 August, and had not fully receded until Christmas. To many locals it is common knowledge that the beginning of the roof on the Visitors' Centre in Main Street was the height in Main Street.
In 2006, historic flood markers were erected at Apex Park and the lawns of the Mildura Rowing Club at Mildura, indicating the height the river reached in 1956. Additional markers are to be erected at various locations along the river from Wentworth to Colignan. Several towns in South Australia also have depth markers showing how high the floodwaters rose.
The town of Wentworth, located on the junction of the Darling and Murray Rivers, erected a statue in 1959 in honour of the Fergie TE20 tractor, responsible for helping to erect a levee around the town which kept floodwaters at bay for months. A tractor rally is also held every five years to celebrate the Fergie.
