Harry Addison March (December 11, 1875 – June 10, 1940) was an early football historian and promoter, as well as a medical doctor.

His father, Henry Clay March, was an officer in the U.S. Army and a close friend to future President William McKinley.

When McKinley advised him that newspaper reporters were "lounge lizards", he studied medicine at George Washington University Medical School and went back to Canton to start a practice.

[3] While in Canton, March played in or watched hundreds of football games featuring the best professionals of the day such as Christy Mathewson, Fielding Yost, Walter Okeson, Knute Rockne and Pudge Heffelfinger.

[6] A squabble with George Preston Marshall, owner of the Boston Redskins, put him out of the National Football League in 1934.
