Sturt Highway is an Australian national highway in New South Wales, Victoria, and South Australia. It is an important road link for the transport of passengers and freight between Sydney and Adelaide and the regions along the route.

Initially an amalgam of trunk routes, the Sturt Highway was proclaimed a state highway in NSW in 1933. In 1955, the route was allocated a National Route number (20). It was included in the National Highway system in 1992, forming the Sydney-Adelaide Link. Sturt Highway is allocated as route A20 for its entire length, the majority of which is a single carriageway, and freeway standard and 6-lane arterial road standard towards its western terminus in Gawler.
