Oliver A. Unger (August 28, 1914 – March 26, 1981) was an American film producer, distributor, and exhibitor. In a 45-year career, he was also a television producer and owner of movie theaters and television stations throughout the United States.

Unger was born in Chicago, of Hungarian descent. His family also lived in New York before moving back in 1920 to the Hungarian capital, Budapest, where his father, Bertram Unger, was a bank president. They returned to New York City in 1926 and Unger attended Columbia Grammar School until his graduation in 1931. Unger earned a Bachelor of Arts degree from Syracuse University in 1935.

Unger was organizing Celebration 33 — a benefit commemorating the thirty-third anniversary of the State of Israel — when he died at the age of 66. He was survived by his wife, Virginia; two sons, Anthony B. Unger and Stephen A. Unger; three daughters: Meryl L. Unger, Dr. Olivia A. Raynor and Victoria R.S. Unger; and a grandson, David A. Unger.

In 1984 the Unger family donated Oliver Unger's collection of personal documents and film production files to the University of Wyoming's American Heritage Center.
