Alexander Moffat (September 22, 1862 – February 23, 1914) was an American football player, coach and official.

After his playing career ended, he remained active in the development of the game as a coach and founding member of football's rules committee.

Moffat was a member of football's Rules Committee for most of his adult life and, in that capacity, helped shape the game during its formative years.

[6] In December 1893, with the game in turmoil as the result of deaths and serious injuries resulting from the game, a formalized Rules Committee was established consisting of Walter Camp of Yale, W. A. Brooks of Harvard, and Moffat as Princeton's representative.

The New York Times urged the three men to "abolish mass plays and other brutal manoeuvres.

"[9] According to an obituary, Moffat for many years after his graduation "acted as coach, umpire and referee and made practice of going to Princeton nearly every season to aid in the training of the football team.
