Drillham is a town and locality in the Western Downs Region, Queensland.
The town was established in 1878 to service the railway and was home to a camp for workers building the bridge over nearby Drillham Creek.
It is thought that the name Drillham is derived from the word 'Delerium', due to the typhoid fever that struck the camp in the 1880s.
In the 2021 census, the locality of Drillham had a population of 113 people.
