Admiral of the Fleet Roger John Brownlow Keyes, 1st Baron Keyes, (4 October 1872 – 26 December 1945) was a Royal Navy officer. As a junior officer he served in a corvette operating from Zanzibar on slavery suppression missions. Early in the Boxer Rebellion, he led a mission to capture a flotilla of four Chinese destroyers moored to a wharf on the Peiho River. He was one of the first men to climb over the Peking walls, to break through to the besieged diplomatic legations and to free them.
