Stephen Sebo (July 15, 1914 – December 10, 1989)[1] was an American football and baseball player, coach, college athletics administrator, and professional sports executive.

During the World War II era, he served in the United States Army Air Forces and was discharged after 5 years with the rank of major.

The highlight of Sebo's tenure at Penn was the 1959 season, in which the Quakers won their first Ivy League championship.

As it turned out, even that wasn't enough to save his job; school officials had already decided before the season that his contract would not be renewed.

After Sebo was fired from his post at Penn following the 1959 season, he became the general manager of the New York Titans, a newly formed team of the upstart American Football League that was renamed as the New York Jets in 1963.
