Adam Graf Tarnowski von Tarnów (4 March 1866 – 10 October 1946) was an Austro-Hungarian diplomat of Polish origin who served during World War I.

Born in Kraków on 4 March 1866 into an old family of the Polish aristocracy, Adam Graf Tarnowski von Tarnów married Princess Marie Światopełk-Czetwertyńska (1880–1965) in Warsaw on 10 September 1901.

[5] Count Tarnowski arrived in the United States on 31 January 1917, as Britain initially refused to grant him safe conduct through the Entente naval blockade.

[6] Furthermore, his arrival coincided with the delivery of the German note announcing the resumption of unrestricted submarine warfare, prompting President Woodrow Wilson to refuse to receive him.

His son, Adam (1892–1956), also became a diplomat and served briefly as Foreign Minister in the Polish government-in-exile in London after World War II.
