Sir Horatio George Powys Townshend (6 February 1780 – 25 May 1843) was a British politician and military officer who served as Member of Parliament (MP) for Whitchurch from 1816 to 1826 and 1831 to 1832.

[2] After his education at Eton, Townshend began his career in the Royal Navy in 1792, but left due to health problems and then entered the Grenadier Guards as an Ensign on 23 September 1795.

[3][4] Townshend embarked with the Grenadier Guards at the Anglo-Russian invasion of Holland in 1799 and accompanied it to Sicily in 1806 and fought at the Battle of Maida.

[7][2] In 1836, Townshend was appointed Lieutenant Governor of the Round Tower at Windsor Castle by King William IV as a reward for his services[8] and held the position until his death.

[3] At his request, his burial pall was dressed in the ceremonial colours of the Grenadier Guards, and his remains were carried to the family vault in Chiselhurst by regimental survivors of Waterloo.
