Prince Rupert of Teck (Rupert Alexander George Cambridge; 24 August 1907 – 15 April 1928) was a member of the British Royal Family, a great grandson of Queen Victoria.
During World War I, the British Royal Family relinquished their Germanic titles, and in 1917 Prince Rupert assumed the title Viscount Trematon, a subsidiary title to his father, who was created Earl of Athlone.
