Thomas Raymond Mason (born September 22, 1956) is an American football coach and former player. He served as the interim head football coach at Southern Methodist University (SMU) for the final 10 games of the 2014 season upon the resignation of June Jones, compiling a record of 1–9. Before that, he had been SMU's defensive coordinator since 2008. Mason also served as the interim head football coach at Boise State University for the first ten games of the 1996 season, compiling a record of 1–9.
As a graduate student, then full-time coach, Mason began his college coaching career at Eastern Washington University, where he worked with linebackers and special teams. He then joined head coach Pokey Allen as defensive coordinator at Portland State University, where the Vikings participated in the NCAA Division II playoffs in six out of seven years with two appearances in the national title game. Following Allen to Boise State as defensive coordinator, Mason coached the 1994 Broncos to the NCAA Division I-A title game. During Boise State's first year as a Division I football program, Mason served as Boise State's interim head coach for the first ten games of the 1996 season while Allen was on leave of absence battling with cancer.
Returning to his alma mater, the University of Nevada, Reno, Mason continued in the role as defensive coordinator. After stints in the Canadian Football League with the BC Lions and the XFL, Mason returned to the collegiate level as linebackers coach at Fresno State University before returning to the role of defensive coordinator at SMU. After his interim head coaching tenure at SMU in 2014, he became the defensive coordinator at the University of Hawaii for the 2015 season but was reassigned to an administrative role before the end of the season.
