Admiral Sir Arthur Kaye Legge KCB (25 October 1766 – 12 May 1835) was an officer of the British Royal Navy who served in three wars and commanded ships in several campaigns. Known as a brave officer and an effective commander, Legge was given several very important postings in the latter part of his career as a rear-admiral, serving in command at Cadiz during the Peninsula War. After retirement, Legge entered royal service, and was in the procession at the funeral of King George III. A very wealthy man, Legge never married, and when he died in 1835 he left large sums of money to his domestic staff.
