The Burnett Highway is an inland rural highway located in Queensland, Australia. The highway runs from its junction with the Bruce Highway at Gracemere, just south of Rockhampton, to the D'Aguilar Highway in Nanango. Its length is approximately 542 kilometres. The highway takes its name from the Burnett River, which it crosses in Gayndah. The Burnett Highway provides the most direct link between the northern end of the New England Highway (at Yarraman, 21 kilometres (13 mi) south of Nanango) and Rockhampton. It is designated as a State Strategic Road (part of Australia’s Country Way) by the Queensland Government.

Burnett Highway is a state-controlled regional road, most of which is rated as "state-strategic". It is defined in six sections, as follows:
