Ernest Tatham Richmond (15 August 1874 – 5 March 1955) was a British architect, who worked in Egypt, Britain, France and the Holy Land.
He qualified as an architect in 1900; but in 1895 had already visited Egypt and assisted Somers Clarke with his book on the temple of Amenhotep III.
From 1902 to 1903 Richmond served in the Royal Engineers on construction works for the British army of occupation in Egypt.
In 1904 he was appointed architect in the Ministry of Works, and rose to be Director of the Department of Towns and State buildings, serving in that capacity until 1911, when he returned to private practice in Britain.
After suffering an injury to his hand from a grenade, he was appointed Architect to the War Graves Service, France, 1917–18.
