David Henry Popper (October 3, 1912 – July 24, 2008) was a diplomat and former United States Ambassador to Cyprus (1969–73) and Chile (1974–77). He was a member and former President of the American Academy of Diplomacy.

Popper was born in Manhattan, NY and raised in White Plains, NY. He and his family were Jewish. Popper entered university at the young age of 15 and graduated valedictorian of his class from Harvard University in 1932 and received a Harvard master's degree in government in 1934. He then went on to join the research staff of the Foreign Policy Association, until the United States entered World War II. Popper worked in Army intelligence at a base in Miami where he traced Axis power movement and influence in Latin America.

David H. Popper began his career as a diplomat when World War II came to an end. In September 1945 Popper joined the US State Department and was assigned to the then new bureau of United Nations affairs. He had a brief scrap with McCarthyism when he was internally investigated because some past associates and organizations of which he had been a member had leftist connections. He was briefly suspended without pay, but after an investigation that involved interviewing his former Boy Scout leaders, he was cleared.

He served as Deputy Director of UN Political and Security Affairs from 1951 to 1954. He served as Director of the Office of Atlantic Political and Military Affairs from 1962 to 1965 alongside Adlai E. Stevenson, then ambassador to the United Nations. He served as US Ambassador to Cyprus (1969–73) during the administration of President Makarios. In 1973 he returned to Washington, DC to serve briefly as Assistant Secretary of State for International Organization Affairs for the duration of that year. His next assignment was to be his most prominent.
