Arnold Allan Cecil Keppel, 8th Earl of Albemarle, GCVO, CB, VD, TD, JP (1 June 1858 – 12 April 1942), styled Viscount Bury from 1891 to 1894, was a British soldier, courtier and Conservative politician.
Lord Albemarle was the eldest son of William Keppel, 7th Earl of Albemarle, and his wife Sophia Mary, daughter of Sir Allan Napier McNab, 1st Baronet, a Canadian politician, and was educated at Eton College. He served with the Scots Guards, achieving the rank of Lieutenant. In 1892 he was returned to Parliament for Birkenhead, a seat he held until 1894 when he succeeded his father in the earldom and took his seat in the House of Lords. Albemarle commanded the Prince of Wales's Own Civil Service Rifles with the rank of Colonel from 1892 to 1901.
After the outbreak of the Second Boer War in October 1899, a corps of imperial volunteers from London was formed in late December 1899. The corps included infantry, mounted infantry and artillery divisions and was authorized with the name City of London Imperial Volunteers. It proceeded to South Africa in January 1900, returned in October the same year, and was disbanded in December 1900. Lord Albemarle was appointed in charge of the infantry division on 3 January 1900, with the temporary rank of lieutenant-colonel in the Army, and served as such until the corps was disbanded. He was mentioned in despatches, received the Queen's South Africa Medal with four clasps, and was in 1900 appointed a Companion of the Order of the Bath (CB) for his services in South Africa. Albemarle was later an Honorary Colonel in the 5th Battalion of the Norfolk Regiment and a Brigadier-General from 1901 to 1906 in the Norfolk Volunteer Infantry Brigade and was awarded the Territorial Decoration.
