Sir Stanley Seymour Argyle KBE, MRCS, LRCP (4 December 1867 – 23 November 1940), was an Australian radiologist and politician.

During World War I, he was consultant radiologist to the Australian Imperial Force in Egypt, France and England.

Between 1923 and 1928, he was Chief Secretary and Minister for Health in the ministries of Harry Lawson, John Allan, Alexander Peacock and William McPherson.

He led the opposition to Ned Hogan's minority Labor Party government, which was unable to cope with the effects of the Great Depression and was heavily defeated at the May 1932 elections.

Argyle, a firm fiscal conservative, held to the orthodox view that in a time of depression government spending must be cut so that the budget remained in balance.

That led a reduction in unemployment relief payments and an increase in taxation revenue, easing the state's financial crisis.

The Country Party leader, Albert Dunstan, was a close friend of the gambling boss John Wren, who was also very close to the Labor leader Tom Tunnecliffe (in the view of most historians, Tunnecliffe was, in fact, under Wren's control[citation needed]).

Henry Bolte, later Victoria's longest-serving Premier, was 27 in 1935, and Dunstan's betrayal of Argyle lay behind his lifelong intense dislike of the Country Party, whom he called "political prostitutes".
