Lieutenant-General Sir Percy Egerton Herbert KCB PC (15 April 1822 – 7 October 1876) was a British Army officer and Conservative politician.

[1] Herbert was made an ensign in the 43rd (Monmouthshire) Light Infantry in January 1840, serving with them in the war on the Xhosa (1851–53), the Orange River Boers expedition, and the battle of Berea.

For his services in the Crimean War he was made an aide-de-camp to Queen Victoria, a Companion of the Order of the Bath (CB) and a colonel (as a brevet rank, on 28 November 1854), and also received knighthoods from the Turkish, Sardinian and French governments.

He commanded the regiment's left wing in the Rohilkhand campaign (being present at the capture of Bareilly and Shahjahanpur) and then the Cawnpore and Fatehpur districts until spring 1859, as well as being sent to pursue Firuz Shah and a body of rebels on the banks of the river Jumna in December 1858.

In March 1867 he was sworn of the Privy Council[4] and appointed Treasurer of the Household in Lord Derby Conservative administration,[5] in which post he remained until December 1868, the last year under the premiership of Benjamin Disraeli.
