Courtenay Charles Evan Morgan, 1st Viscount Tredegar, OBE, VD (10 April 1867 – 3 May 1934), was a British peer.
Morgan was the eldest son of the Honourable Frederick Courtenay Morgan, of Ruperra Castle, third son of Charles Morgan, 1st Baron Tredegar. His mother was Charlotte Anne, daughter of Charles Alexander Williamson, of Lawers, Perthshire. He succeeded his uncle Godfrey Morgan, 1st Viscount Tredegar, as third Baron Tredegar in 1913.
Tredegar was appointed a captain in the Royal Monmouthshire Royal Engineers on 30 December 1891, and was later promoted an honorary major. In early 1900 he was Aide-de-camp to Sir Thomas Fraser, Commandant Royal School of Military Engineering at Chatham and Commanding the Thames District.
One of Lord Tredegar's first acts after his succession was to purchase the steam yacht Liberty, which almost immediately was requisitioned by the Royal Navy for use as a hospital ship. He left his home and went back to war, taking command of his yacht for the first part of the war. After the end of hostilities, he embarked on a world cruise, eventually going around the world twice during which he visited every colony in the British Empire and every state in the Commonwealth.
In 1926 the viscountcy was revived when he was created Viscount Tredegar, of Tredegar in the County of Monmouth. He is not recorded as having spoken in the House of Lords. In 1933 he was appointed Lord Lieutenant of Monmouthshire, a post he held until his death the following year.
