Thomas Davies FRS FLS is a British Army officer, artist, and naturalist.
He was born c. 1737 in Shooter's Hill, England and died 16 March 1812 in Blackheath. He rose to the rank of Lieutenant-general in the Royal Artillery. He studied drawing and recorded military operations in water-colours during several military campaigns in North America. He later became a noted artist and naturalist. He was the first to illustrate and describe the superb lyrebird.
His work was not well known until after a 1953 auction from the Earl of Derby's library. His paintings were later shown as part of a major exhibition, 2 July – 4 September 1972, at the National Gallery of Canada.
