Sugar Research Institute, Historic research facility in West Mackay, Queensland, Australia

Sugar Research Institute is a former research station at 239 Nebo Road, West Mackay, designed by Karl Langer and built in 1953 by Don Johnstone. Its eastern wing was the first section; a western wing, planned by Harold Brown in 1963, opened in August 1966.

Sugar Research Limited was established in 1949 as a cooperative effort to advance Australian sugar production through organized research. The founding brought together industry members who recognized the need for centralized technological development and knowledge sharing.

The name honours Dr Henry William (Bill) Kerr, the Bureau of Sugar Experiment Stations director from 1933 to 1943, who became the institute's first director in 1949 and led it until 1961. Kerr introduced replicated field experiments with statistical analysis to Australian sugar agriculture and served in the Queensland Society of Sugar Cane Technologists from its founding in 1929 until his death in 1992.

The former research station stands at 239 Nebo Road, West Mackay, on the city's western edge. It is a heritage-listed building rather than a staffed visitor attraction, so the two wings are seen from outside. The eastern wing dates from 1953, the western wing from 1966.

The board chose Mackay for the central laboratories because in 1949 it was the largest sugar-growing district and the geographical centre of the Australian industry. Sugar Research Limited was incorporated on 22 February 1949 with 22 companies representing 24 mills as original subscribers.
