Martin John O'Connor (May 18, 1900 – December 1, 1986) was an American prelate of the Roman Catholic Church. He served as rector of the Pontifical North American College (1946–64) and president of the Pontifical Council for Social Communications (1948–71).

Martin O'Connor was born in Scranton, Pennsylvania, to Martin John and Belinda Catherine (née Caffrey) O'Connor. His parents died when he was young. He received his early education at James Madison Elementary School, but was later transferred to the district's administration building to attend advanced classes. He entered St. Thomas High School at age 12, and enrolled at St. Thomas College three years later. He graduated from St. Thomas with a Bachelor of Arts degree in 1918.

O'Connor then began his studies for the priesthood at St. Mary's Seminary in Baltimore, Maryland. He continued his studies at the Catholic University of America in Washington, D.C. While a student at the Catholic University, he enlisted in the Army after the United States entered World War I. He resumed his studies when the armistice was signed. O'Connor was then sent to study at the Pontifical North American College in Rome. He earned a doctorate in theology from the Urban College of Propaganda in 1925.
