Ntare V of Burundi (born Charles Ndizeye, 2 December 1947 — 29 April 1972) was the last king of Burundi from July to November 1966. Until his accession, he was known as Crown Prince Charles Ndizeye. After a Hutu-led coup attempt in October 1965, his father, Mwambutsa IV withdrew to Switzerland. In March 1966 Mwambusta IV designated his only surviving son to exercise his powers on the spot. The Crown Prince then formally deposed his father and his father's government in July 1966. King Ntare himself was deposed, later the same year, in a military coup led by Michel Micombero; the former king went into exile in West Germany and later Uganda.

His mother was Queen Baramparaye (1929—2007); he had one half-brother (Prince Louis Rwagasore, assassinated 1961 whilst Prime Minister, and two half-sisters; Princess Rosa Paula Iribagiza (born 1934) and Princess Regina Kanyange (died 1987). Ntare V was educated at Institut Le Rosey in Switzerland.

Ntare V returned to Burundi in March 1972. Soon afterwards the Hutus began an uprising against the government and established the short-lived state of Martyazo. Uganda’s president, Idi Amin, claimed he received a written guarantee from President Micombero that Ntare could return to Burundi and live there as a private citizen. Using the helicopter at his disposal from the Uganda chief of state, Ntare arrived where he and his ancestors had ruled as kings. Within a few hours he was put under house arrest in the former palace in Gitega. Soon after, an official radio broadcast proclaimed that Ntare was trying to instigate a mercenary invasion of Burundi to take back rule. Some ministers favored that he would be kept under restricted protection in Gitega, while others wanted him dead. The situation was unofficially resolved when Ntare was assassinated sometime between Saturday evening, April 29, and the following morning, under circumstances which are still unclear.
