Admiral Chung Tấn Cang was a commander of the Republic of Vietnam Navy between 1963 and 1965.

The Republic of Vietnam Navy (RVNN; Vietnamese: Hải quân Việt Nam Cộng hòa - HQVNCH; was the naval branch of the South Vietnamese military, the official armed forces of the former Republic of Vietnam from 1955 to 1975. The early fleet consisted of boats from France; after 1955, and the transfer of the armed forces to Vietnamese control, the fleet was supplied from the United States. With American assistance, in 1972 the VNN became the largest Southeast Asian navy and, by some estimates, the fourth largest navy in the world, just behind the Soviet Union, the United States and the People's Republic of China, with 42,000 personnel, 672 amphibious ships and craft, 20 mine warfare vessels, 450 patrol craft, 56 service craft, and 242 junks. Other sources state that VNN was the ninth largest navy in the world. The Republic of Vietnam Navy was responsible for the protection of the country's national waters, islands, and interests of its maritime economy, as well as for the co-ordination of maritime police, customs service and the maritime border defence force.
