The Pioneer River is a river system in Queensland, Australia that flows through the city of Mackay. 120 km in length, the river rises in the Pinnacle Ranges near Epsom, 63 km south-west of Mackay. The river flows in a northerly direction into the Pioneer Valley, one of Australia's richest sugar cane areas. At Mirani, the river swings around to the east before flowing into the Pacific Ocean at Mackay.
The river is too shallow for navigation, drying sandbanks encountered only a few kilometres upstream of the river mouth. The river is prone to flooding, most recently in February 2000 when a height 6.85 metres (classed as moderate flooding according to the Bureau of Meteorology) was recorded at a gauge in the centre of Mackay. After the devastating Mackay cyclone of January 21, 1918, the river was flooded for weeks.
The longest tributary of the Pioneer River is Cattle Creek.
