The 1974 Brisbane flood occurred in January 1974 in Brisbane, Queensland, Australia, when waterways in the city experienced significant flooding. The Brisbane River, which runs through the heart of the city, broke its banks and flooded the surrounding areas.

14 people lost their lives, including 10 people who were drowned in the suburbs of Yeronga, Newmarket, St Lucia, and the city of Ipswich upriver and to the West.
After the flood, a series of flood mitigation measures were implemented in Southeast Queensland.
The flood was a defining event for a generation of Brisbane residents. 8,500 homes were flooded in Brisbane and Ipswich. 6000 of these could not be recovered from an inland sea of 200 square kilometres (20,000 ha) formed by the flood waters.
