Arthur Adolf, Count of Posadowsky-Wehner, Baron of Postelwitz (German: Arthur Graf von Posadowsky-Wehner Freiherr von Postelwitz, 3 June 1845 – 23 October 1932) was a German conservative statesman.
He served as Secretary for the Treasury (1893–1897), Secretary of the Interior, Vice Chancellor of Germany and Prussian Minister of State (1897–1907).
Born to Silesian nobility, the son of a judge, Posadowsky-Wehner studied law in Berlin, Heidelberg and Breslau and earned a doctorate in law in 1867.
He subsequently acquired an agricultural property, and entered politics in 1871, when he became a member of the province government in Posen.
In 1882 he became a member of the Parliament of Prussia, and was appointed Landeshauptmann of Posen in 1885.
Posadowsky was a crucial figure for the election reform in 1903.
He took care of a new voting technique to protect the secrecy of the ballot for the German parliament.
Posadowsky-Wehner was the candidate of the German National People's Party for the Presidency of Germany in 1919, but he lost to Friedrich Ebert.
