Lieutenant-Colonel Sir William Alexander Gordon Gordon-Cumming, 4th Baronet (20 July 1848 – 20 May 1930) was a Scottish landowner, soldier, adventurer and socialite. A notorious womaniser, he is best known for being the central figure in the royal baccarat scandal of 1891. After inheriting a baronetcy he joined the Army and saw service in South Africa, Egypt and the Sudan; he served with distinction and rose to the rank of lieutenant-colonel. Something of an adventurer, he also spent time hunting in the US and India.
