Arthur Alfred Lynch (16 October 1861 – 25 March 1934) was an Irish Australian civil engineer, physician, journalist, author, soldier, anti-imperialist and polymath.

He served as MP in the UK House of Commons as member of the Irish Parliamentary Party, representing Galway Borough from 1901 to 1902, and later West Clare from 1909 to 1918.

His father, John Lynch, was an Irish Catholic surveyor and civil engineer and his mother Isabella (née MacGregor) was Scottish.

[1] Arthur Lynch was educated at Grenville College, Ballarat, (where he was "entranced" by differential calculus) and the University of Melbourne, where he took the degrees of BA in 1885 and MA in 1887.

[3] In contrast, Antony O'Brien's fictional Bye-Bye Dolly Gray, is kinder to Lynch's showy South African exploits and his uitlanders.

From South Africa, Lynch went to the United States, and then returned to Paris, from where he again stood for Galway Borough in November 1901 and was elected in his absence as MP.

Lynch wrote and published a large number of books ranging from poetry to a sophisticated attempt to refute Albert Einstein's theory of relativity.

E. Morris Miller, himself a professor of philosophy, mentions Lynch's "high reputation as a critical and philosophical writer especially for his contributions to psychology and ethics" (Australian Literature, p. 273).
