Henry Frederick Stephenson (18 September 1790 – 30 July 1858) was a British Whig politician and officer of arms.
He was the illegitimate son of Charles Howard, 11th Duke of Norfolk.
He was appointed Falcon Herald Extraordinary and in 1815 was part of the mission to give the Garter to the Tsar Alexander I of Russia.
On that occasion the emperor gave a gem ring to Stephenson, who was so pleased with this mark of favour that he was granted a supposed 'augmentation of honour' to his arms of a canton charged with the letter A within a gem ring.
After leaving Parliament, he held a variety of minor offices.
