Richard Randolph Machattie (1843 - 27 December 1902) was an Australian politician.
He was born at Bathurst to a medical doctor, and he attended Bathurst Grammar School. He became a government surveyor, generally in the Carcoar and Bathurst districts. In 1882 he was elected to the New South Wales Legislative Assembly for Bourke, but he was defeated in 1885. A squatter at Brewarrina from 1884, the 1890s drought forced him to abandon his properties. Machattie died at Bathurst in 1902.[1]
