Farleigh is a rural town and locality in the Mackay Region, Queensland, Australia.

The Bruce Highway traverses through the locality from the south-east to the west, passing through the town.

In 1900 the mill was sold to Farleigh Estate Sugar Co Ltd in 1900 and developed so that it could replace a number of the local mills: Ashburton, The Cedars, Coningsby, Pioneer, Richmond, Nindaroo, Habana and Dumbleton.

After Farleigh Estate Sugar Co Ltd went bankrupt in 1926, the mill was purchased by a co-operative of local sugarcane growers.

In November 1987 Farleigh Mill merged with other Mackay district mills to create the Mackay Sugar Co-operative Association Ltd.[6] Coningsby State School opened on 24 November 1884.
