The university said Roethlisberger received his bachelor's degree in education and joined nearly 600 students during a commencement ceremony on campus. His wife, parents and grandmother attended.
The 30-year-old quarterback, who has led the Steelers to two Super Bowl titles, played football for the university from 2001 to 2003, setting several school passing records.
An associate dean said Roethlisberger was four courses short of graduation when he jumped to the NFL. He completed those courses over several years and finished this spring.
Roethlisberger said he felt it was important to finish his classes to illustrate the value of getting an education.
