The Leichhardt Highway is a major transport route in Queensland, Australia. It is a continuation northward from Goondiwindi of the Newell Highway, via a 2.0-kilometre (1.2 mi) section of the Cunningham Highway.
It runs northward from Goondiwindi for more than 600 kilometres until its termination at the Capricorn Highway near the small town of Westwood.
The highway is a state-controlled strategic road, except for the section concurrent with the Gore Highway, which is a state-controlled part of the National Network.
