Alexander Fuller-Acland-Hood, 1st Baron St Audries PC, known as Sir Alexander Fuller-Acland-Hood, Bt, until 1911, was a British Conservative Party politician. He served as Parliamentary Secretary to the Treasury under Arthur Balfour from 1902 to 1905.

The Parliamentary Secretary to the Treasury is the official title of the most senior whip of the governing party in the Parliament of the United Kingdom. Today, any official links between the Treasury and this office are nominal and the title of the office can be seen as a sinecure that allows the incumbent to draw a Government salary, attend Cabinet, and use a Downing Street residence, traditionally 12 Downing Street.
