The Field River is an urban watercourse located in the southern suburbs of Adelaide in the Australian state of South Australia.
Part of the Onkaparinga River catchment that drains the western slopes of the Mount Lofty Ranges, the Field River has a total area of 55.3 square kilometres (21.4 square miles) and drains the Happy Valley Reservoir, part of Main South Road and the Southern Expressway. Suburbs bordering the river include Hallett Cove, Reynella, Shiedow Park, Trott Park, Happy Valley and Woodcroft.
The stream flow of the Field River is highly seasonal and variable with an average annual runoff of 5,100 million litres (1.1×109 imperial gallons; 1.3×109 US gallons). The majority of the stream can dry out completely during summer, staying that way well into autumn. The final portion of the river is spring fed and flows into the Gulf St Vincent all year round.
The Field River flows through or is bordered by the City of Marion and City of Onkaparinga. The lower reaches of the river ran through private property owned by the Sheidow family until 1993 when the land was sold for housing development and became Cove Point in the suburb of Hallett Cove. The stretch of the river further inland on the south eastern side of Lonsdale Road is presently in private ownership. This parcel of land has been identified as being an important part of the proposed Great Southern Urban Forest of Adelaide.
