Philip P. DiStefano (born September 21, 1946)[1] is an academic administrator who serves as the 11th chancellor of the University of Colorado Boulder since May 2009.

He has taught at the University of Colorado, Boulder since 1974, and holds the Quigg and Virginia S. Newton Endowed Leadership chair.

[9][10] After the university selected Justin Schwartz as his successor, DiStefano officially retired from his position on July 1, 2024.

[11] In 2017, DiStefano was suspended without pay for ten days for failing to report domestic abuse allegations against an assistant football coach at the school.

George and MacIntyre were both ordered to pay $100,000 to domestic violence charities as a result of these allegations, a punishment that was met with some controversy as their base salaries were more than $2 million.

[16] The University of Colorado Boulder, however, held classes in person that day and did not send alerts to its students until 10 A.M., nearly two hours after the police became involved.
