Hamilton Hartridge FRS (7 May 1886 – 13 January 1976) was a British eye physiologist and medical writer. Known for his ingenious experimentation and instrument construction abilities, he designed what is called the Hartridge Reversion Spectrometer. This was used for pioneering studies on haemoglobin oxygen-binding studies.

Hamilton Hartridge FRS was educated at Harrow and King's College, Cambridge, where he became a fellow from 1912 to 1926. He graduated in medicine from St George's Hospital in 1914, serving during the war as an experimental officer at RNAS Kingsnorth. In 1916 he married Kathleen Wilson. After the war he stayed in Cambridge University as lecturer in special senses and senior demonstrator in physiology. He gained a reputation as an ingenious experimenter, constructing, for example, the continuous-flow apparatus for measuring the rates of very fast reactions, as well as working to revise established medical textbooks. From 1927 to 1947 he was professor of physiology at St Bartholomew's Hospital, and from 1947 to 1951 director of the vision research unit of the Medical Research Council. He was president of the Quekett Microscopical Club from 1951 to 1954 and he was elected an Honorary Member in 1952. He was Gresham Professor of Physic. In 1946 he delivered the Royal Institution Christmas Lectures entitled Colours and how we see them.
