The Honourable Algernon Fulke Egerton (31 December 1825 – 14 July 1891), known as Algernon Leveson-Gower until 1833, was a British Conservative politician from the Egerton family.

Egerton was the third son of Francis Egerton, 1st Earl of Ellesmere, younger son of George Leveson-Gower, 1st Duke of Sutherland. His mother was Harriet Catherine, daughter of Charles Greville, while George Egerton, 2nd Earl of Ellesmere, and the Honourable Francis Egerton were his elder brothers.^[1]

On 16 May 1860 he was commissioned as Lieutenant-Colonel Commandant of the 3rd Manchester Rifles, a Rifle Volunteer unit recently raised by his political colleague John Snowdon Henry. He later became its Honorary Colonel, and in 1875 his nephew, Francis Egerton, 3rd Earl of Ellesmere became lieutenant-colonel commandant.^[2][3]
