Thomas Allen Holmoe (born March 7, 1960) is an American college athletics administrator and former football player and coach.

After retiring from playing, Holmoe entered the coaching ranks, having been urged by LaVell Edwards to return to BYU as a graduate assistant.

In 1992, Holmoe accepted an offer from Bill Walsh to join his staff at Stanford University as the defensive backs coach.

Shortly afterward, the Bears were found guilty of major NCAA violations when it emerged that a professor retroactively added two football players to a class he had taught the previous spring in order to keep them eligible.

He hired head football coach Bronco Mendenhall, who returned BYU's football team to national prominence, and head men's basketball coach Dave Rose, who led BYU's men's basketball team to consistent conference championships and NCAA tournament appearances.

During the COVID-19 pandemic, BYU's independent football schedule was drastically altered at the last minute as several conferences decided to play league-only games.

[10] In February 2025, Holmoe announced he would retire from serving as AD at the conclusion of the 2024-2025 sports season, capping two decades in the role.

[11][12] Holmoe is a member of the Church of Jesus Christ of Latter-day Saints, converting from Lutheranism six years after leaving BYU.
