Stuart is a locality in the Riverland region of South Australia.

[2] Stuart is crossed by the Goyder Highway and bounded on its southern side by the Murray River.

Despite the river flowing past the south of the locality, it is in an area of very low rainfall not reliable for farming.

Stuart is the site of ElectraNet's North West Bend electricity substation.

If they are constructed, Stuart will be crossed by the Project EnergyConnect electricity interconnector joining the South Australian and New South Wales electricity grids.
